Underwhelmed by Deep Seek

Given Gemini’s obvious attempts to put a thumb on the scale, I thought it would be interesting to see how Deep Seek did when posed exactly the same questions. The results so far are inconclusive and underwhelming.

Given the average length in years of a human generation, and assuming that the Chimpanzee-Human Last Common Ancestor lived 9 million years ago, how many human generations has it been since the Chimpanzee-Human Last Common Ancestor?

UPDATE: The version made available by Gab did better.

 The user is asking how many human generations have passed since the Chimpanzee-Human Last Common Ancestor (CHLCA), which was 9 million years ago. They mention using the average length of a human generation. Hmm, so first I need to figure out the average generation length and then divide 9 million by that number.

Wait, but what exactly is considered a generation here? Is it the average age of parents when they have offspring? I think that’s typically how generation length is defined. For humans, I remember reading that a generation is roughly 20 to 30 years. But I should verify the exact value. Maybe different sources use slightly different numbers. For example, some studies might use 25 years as an average. Let me recall. The Generation length can vary depending on the context—demographic, genetic, or historical. In population genetics, they often use 25 to 30 years. But I need to pick a standard value here. Maybe the user expects an approximate answer, so perhaps 25 years is a commonly cited average. Alternatively, if I check some references, the OECD uses 25 years for a generation, and some genetic studies use around 25-30. Let’s go with 25 years as a middle ground. So if each generation is 25 years, then the number of generations would be 9,000,000 divided by 25. 

By the way, that was significantly reduced from the original wall of text. Deep Seek really agonizes over its answers.

Scientists have measured a genetic difference between modern humans and modern chimpanzees measured in DNA base pairs. How large is that difference and how many genetic fixation events are required to account for it?

First, I remember that humans and chimpanzees share a very high percentage of their DNA, often cited as around 98-99% similarity. But the exact figure can vary depending on the study and what’s being measured. For example, some sources say 98.7%, others might say 95% when considering insertions and deletions (indels) and other structural variations. So the actual number of differing base pairs would depend on the total genome size and the percentage difference.

The human genome is roughly 3 billion base pairs long. If we take the commonly cited 1.2% difference (from the 98.8% similarity), that would be 3,000,000,000 * 0.012 = 36 million base pairs different. But wait, I need to check if that includes all types of variations or just substitutions. Because indels (insertions or deletions) can cause more significant differences. For example, a study in 2005 suggested that the actual single nucleotide substitutions account for about 1.23% difference, and when including indels, the total difference increases to around 4% or higher. But maybe more recent studies have updated these numbers.

Alternatively, the 1.2% figure is often used for single nucleotide polymorphisms (SNPs), while structural variations add more. However, the user specifically mentions “DNA base pairs,” which might refer to single nucleotide differences. But it’s a bit ambiguous. Let me confirm: DNA base pair differences can include substitutions, insertions, deletions. So total difference would be all those.

So to summarize:

  1. Genetic difference: ~35-40 million base pairs (considering SNPs and small indels), or higher with structural variations.
  2. Fixation events: Approximately equal to the number of differences, so ~35-40 million, as each difference is a fixation in one lineage.

However, it’s important to note that some studies might present different numbers. For example, a commonly cited figure is about 35 million single nucleotide differences and around 5 million indels, totaling 40 million. Therefore, the answer would be that the genetic difference is approximately 40 million base pairs, and around 40 million genetic fixation events are required. </Thinking>

The genetic difference between modern humans and chimpanzees, measured in DNA base pairs, is approximately 35–40 million differences when considering single nucleotide substitutions (SNPs) and small insertions/deletions (indels). This represents about 1.2–1.3% divergence in aligned sequences of the ~3 billion base pair genome. Including larger structural variations (e.g., duplications, inversions), the total divergence increases to 4–5%, but these are less often counted as individual base pair differences.

For genetic fixation events (mutations that become universal in a population), the total number required to account for these differences is roughly equivalent to the number of observed differences. This is because each divergence represents a fixation event in one lineage (human or chimpanzee) since their split from the CHLCA ~7–9 million years ago.

Summary:

  • Base pair differences: ~35–40 million (SNPs and indels).
  • Fixation events: ~35–40 million (assuming each difference arose and fixed in one lineage).

Generational Length Update

It was brought to my attention that even the increase from 20 years to 27.5 years was insufficient, given the scientific evidence updating the observed length of a historical human generation:

As early as 1973, archaeologist Kenneth Weiss questioned the accepted 20 and 25-year generational intervals, finding from an analysis of prehistoric burial sites that 27 years was a more appropriate interval, but recognizing that his conclusion could have been affected if community members who died away from the village were buried elsewhere. When assigning dates to anthropologically common ancestors 50 or more generations in the past, using the “accepted” 20 or 25 years as a conversion factor can produce substantial underestimates of the time interval. Nevertheless, those unsupported values continue in use, even in recent scientific papers.

In the first of the three more recent studies of generation length, sociologist Nancy Howell calculated average generational intervals among present-day members of the !Kung. These are a contemporary hunter-gatherer people of Botswana and Namibia whose life style is probably close to that of all our pre-agricultural ancestors in the dim past. The average age of mothers at birth of their first child was 20 and at the last birth 31, giving a mean of 25.5 years per female generation — considerably above the 20 years often attributed to primitive cultures. Husbands were six to 13 years older, giving a male generational interval of 31 to 38 years.

A second study by population geneticists Marc Tremblay and Hélène Vézina was based on 100 ascending Quebec genealogies from 50 randomly selected couples married between 1899 and 1974. The data came from BALSAC, an inter-university computerized research database at the University of Quebec at Chicoutimi, extracted from Quebec parish baptism and marriage registers going back to the 1600s. With an average depth of nine generations, but extending as far back as 12 or 13 generations, their sample included 10,538 generational intervals. They took as the interval the years between parents’ and children’s marriages, which averaged 31.7 years.

They also determined separate father-son and mother-daughter generational intervals, from lines that included at least five consecutive all-male or all-female generations. These averaged 35.0 years for male generations, 28.7 years for female years.

Biological anthropologist Agnar Helagason and colleagues, in the last of the three studies, used the Icelandic DeCODE genetics database, containing lineages of most Icelanders back two centuries, and much longer for many families. They computed separate patrilineal and matrilineal generation intervals over different lengths of time, to see if that produced a difference. The first values included only lines to ancestors who live in the 1848-1892 time frame, including three to five generations. Then they calculated interval lengths back to ancestors born between 1692 and 1742, extending them to a length of seven to nine generations. The results showed the most recent generations were a little shorter in length than more distant ones — the opposite of what the conventional view holds.

The female line intervals were 28.12 years for the most recent generations, 28.72 years for the whole lineage length. Male-line lineages showed a similar difference, 31.13 years for the recent generations, 31.93 overall. Based on their Icelandic findings and those of the Quebec study, they recommended using a female-line interval of 30 years and a male interval of 35 years.

This updated scientific evidence therefore requires a recalibration of the percentage of the known genetic distance for which evolution by natural selection could mathematically account.

Digging Ever Deeper

A reader who has access to the professional Gemini 1.5 AI was kind enough to ask it several of the questions concerning MITTENS that I requested from its dumbed-down public version; one thing that was interesting was that it included the actual observed distance in DNA between humans and chimpanzees, not just the protein-encoded sections of the genomes. He sent me a link to the results, a portion of which I’ve pasted here:

When you say that there is a 4 percent difference in DNA between humans and chimpanzees, approximately how many genetic fixation events are required to account for that difference?

It’s challenging to give an exact number of fixations corresponding to a 4% genetic difference between humans and chimpanzees. Here’s why:

  • Not just single base changes: The 4% difference encompasses various genetic alterations:
  • Single nucleotide polymorphisms (SNPs): These are single base pair changes.
    Insertions and deletions (indels): Where segments of DNA are added or removed.
    Structural variations: Larger-scale rearrangements, duplications, or losses of DNA segments.
    Varying impact: Each type of change has a different impact. A single SNP in a critical gene might have a large effect, while many SNPs in non-coding regions might have little functional consequence.
  • Unknown ancestral state: Reconstructing the exact genome of the CHLCA is difficult, making it hard to trace the precise number of changes on each lineage.

However, we can make a rough approximation:

  • Genome size: The human genome is roughly 3 billion base pairs.
  • 4% difference: This equates to 0.04 * 3,000,000,000 = 120,000,000 base pair differences.
  • If we assume, for simplicity, that most of these differences are due to single nucleotide fixations, then 120 million fixations would be a crude estimate.

Important caveats:

  • Oversimplification: This ignores indels and structural variations, which contribute significantly to the 4% difference.
  • Non-uniform distribution: Changes aren’t evenly distributed. Some regions have higher variability, while others are highly conserved.
  • Functional impact varies: Not all fixations have the same functional impact.

In conclusion: While a precise number is elusive, the 4% difference likely translates to millions of genetic changes, including fixations, indels, and structural variations. This highlights the complexity of the evolutionary process and the multitude of genetic changes contributing to the differences between humans and chimpanzees.

Given the maximum possible number of fixation events since the Chimpanzee-Human Last Common Ancestor is 204 according to your earlier reply, is it rational to assert that evolution by natural selection has accounted for 120 million fixation events in the last nine million years?

You’re right to question that! It indeed seems contradictory. Here’s why the two numbers don’t match up and what we can learn from it. The 204 fixations figure was a highly simplified calculation. It assumed:

  • A constant rate of fixation (1,600 generations per fixation).
  • Only single gene fixations, ignoring other types of genetic changes.

Why the huge discrepancy?

We underestimated the complexity of genetic change. The 4% difference between humans and chimps includes many types of changes beyond single gene fixations. Structural variations, indels, and changes in gene regulation are crucial and likely account for a large portion of the genetic divergence.

Now, what’s important here is that even as the minimum possible number of generations has been reduced from 1,600 observed for the e. coli bacteria to 64 for the Lambda virus, the genetic difference has been rising from 30 million to 120 million due to the need to account for the fixation of the full range of the observed differences in the DNA, not just those observed in protein-coding DNA.

Furthermore, my estimate of 20 years per generation was apparently too minimal, the professional AI views a standard generation as being 27.5 years. Thus, the original equation needs to be revised as follows:

CHLCA
Years: 9,000,000
Years per generation: 27.5
Generations per fixed mutation: 64
Years per fixed mutation: 1,760
Maximum fixed mutations: 5,114
Mutations required: 120,000,000
% attributable to evolution by natural selection: 0.00004 or four-thousandths of one percent.

All that switching from the bacteria to the simpler structure of the virus accomplishes is to remove one decimal point from the improbability, from one in 240,000 to one in 23,465. However, it is obviously not even possible for a genetic mutation to fix in the entire breeding human population in 27.5 years, or any faster than that. This is the hard place that none of the evolutionists feverishly attempting to find faster mutational fixation rates have realized is there; the number of generations per fixed mutation is almost certainly closer to the 8,170 suggested by the Genghis Khan heritage than the 64 observed for the Lambda virus, although it’s probably even higher than that.

But regardless, even with the faster observed fixation rate, claiming that you believe evolution by natural selection can explain the differences between chimpanzees and humans is mathematically akin to saying that you believe your friend who says he drove the 2,790 miles that separate New York City from Los Angeles in six seconds.

Mailvox: Fixation and Physicists

Frank Tipler, the Professor of Mathematical Physics at Tulane, did a little digging and found a claim by Richard Lenski to have observed fixation in a virus taking place 10 times faster than he observed in his famous experiments with E. coli bacteria.

It occurred to me that the fastest rate of genetic fixation should occur in viruses, since they are the least complicated organisms that be considered “living.”

Here’s a post by Richard Lenski, in which he SEEMS to claim that his students observed fixation of a group of four mutations in the Lambda virus in 8 days. The life cycle of the Lambda virus is 45 minutes, so 8 X 24 X 60/45 = 256 generations. In a replication experiment with a larger population, he SEEMS to say it took 3 weeks, or 21 X 24 X 60/45 = 672 generations.

Either is faster that Lenski’s E. coli fixation time of 1,600 generations per mutation.

But since there are 4 mutations fixed, we have, for each mutation, an even faster rate: 256/4 = 64 generations per individual mutation, or 672/4 = 168 generations per individual mutation. Lenski argues for strong selection pressure to account for the rapid rate.

I think that these numbers would be the true fastest observed mutation fixation rate. Still too slow to account for the human-chimp fixed gene difference in 9 million years.

Duly noted and much appreciated. Just to keep things in perspective, while this faster observed rate theoretically reduces the minimum number of years per fixed mutation from 32,000 to 3,360, that only increases the maximum number of fixed mutations since the Last Chimp Human Common Ancestor to 2,679, which is still considerably short of the observed 15,000,000 fixations required.

Achieving Faster Fixation

A few SGers were confused by the way in which the 2009 paper for the e. coli experiment didn’t provide clear numbers regarding what was, and what was not, a fixation event. And, as it turns out, considerably more work has been done in this space since 2009, and it’s evident that at least a few scientists are growing concerned about the obvious implications of the time, in generations, that is required for mutational fixation, presumably due to its obvious implications for the impossibility of evolution by natural selection. In fact, some are even attempting to prove that fixation is not required for adaptation, in a quixotic illustration of the way in which they still don’t truly understand the extant nature of the problem MITTENS poses for TENS.

Any understanding of an evolutionary process requires the understanding of the particular components that make up that evolutionary process. Darwin wrote about these evolutionary processes in his book, “On the Origin of Species”[1]. From this text, we get a particular quote that describes these processes: “For it should be remembered that the competition will generally be most severe between those forms which are most nearly related to each other in habits, constitution and structure. Hence all the intermediate forms between the earlier and later states, that is between the less and more improved state of a species, as well as the original parent-species itself, will generally tend to become extinct. So it probably will be with many whole collateral lines of descent, which will be conquered by later and improved lines of descent. If, however, the modified offspring of a species get into some distinct country, or become quickly adapted to some quite new station, in which child and parent do not come into competition, both may continue to exist.” Darwin recognized that two processes can occur during evolution, competition (what Darwin also calls the struggle for existence) and adaptation. Many papers have been written about the mathematics of competition. Some of the many examples were written by Haldane et al. [2-5]. Here, we will address both the mathematics of competition and the mathematics of adaptation. In this paper, we consider a particular experimental evolutionary model, the Lenski E. coli long term evolution experiment (LTEE) [6] and the particular evolutionary components which cause the experiment to act in its manner. And to address why it takes so many generations for each fixation and adaptation step. A model for fixation was presented in the following paper BH Good, et al. and edited by Richard Lenski where they discuss these issues [7]…

In this study, we make the simplifying assumption that the distribution of variants in the entire 10ml test tube is identical to the distribution of variants in the 0.1ml sample. The other selection process is the natural selection process that occurs as the different variants replicate where the more fit variant ultimately substitutes for the less fit variants over generations. This is due to the differences in the relative fitness of the different variants in the population. These two selection processes must be combined to correctly describe the fixation process in the LTEE. But the fixation process does not describe the adaptation process. Adaptation (an improvement in fitness) occurs when another beneficial mutation occurs on the more fit variant. The improvement in fitness of a particular variant is dependent on the absolute fitness of that variant to replicate because the random trial for improvement in fitness is the replication and the frequency at which the beneficial mutation occurs is given by the mutation rate. This is a binomial probability problem, that is, does the beneficial mutation occur or does it not occur with that replication. The mathematical model to describe this part of the evolutionary process is given by the mathematics of random mutation and natural selection [10]. The probability of that beneficial mutation occurring on the more fit variant is dependent on the number of replications of that variant. This value will be tabulated in the mathematical model of fixation. The key point to understand in the evolutionary process is that fixation is not a requirement for adaptation. If the carrying capacity of the environment is sufficient to allow for the number of replications required to give a reasonable probability of a beneficial mutation occurring on some variant, then fixation is not needed for adaptation.

Have you spotted the problem yet? Anyhow, the experiment provided a way to test how long it took a mutation to fixate, and the results were considerably faster than the 1,600 generations previously indicated. In fact, they managed to reduce the number of generations to fixation to a range between 119 and 497!

However, the table raises an obvious question. What is this k that appears to be directly related to the number of generations required? And aye, there’s the rub.

 If that weight factor is 2, that means that variant is doubling in number every generation.

So, k=2 is a very strong replication weight factor. And yet, even with it cranked up to an unnaturally high rate, it’s still insufficient to reduce the number of generations to fixation to a sufficient level. And a more realistic replication weight factor that is more reflective of the genetic changes we can observe in real-time from one generation to the next is obviously going to be much lower, and in line with those previously reported.

But all of this frantic activity to prove that fixation is not necessary for adaptation is misplaced anyhow, because the problem is not adaptation, but the observable genetic distance that consists of historical fixation events separating one species from another. One can certainly prove that it’s not necessary to travel from point A to point B in a boat in order to cross a river, but that proof will never change the previously measured width of the river.

Darwin’s Dead

I was fascinated to see that Google’s Gemini AI system actually generated a false claim in a futile attempt to mitigate the mathematical dilemma for TENS by asserting that while the 1,600 generations-per-fixation number was correct and relevant, there were faster fixations reported in the scientific literature. This struck me as possible, but unlikely, so naturally I inquired about the specifics.

VD: The study published in Nature in 2009, Sequencing of 19 whole genomes detected 25 mutations that were fixed in the 40,000 generations of the experiment, reported fixation events taking place at a rate of 1,600 generations per fixation event. Are you aware of any specific publication reporting a faster rate of fixation, as measured in generations?

GEMINI AI: You’re referring to a key finding from Richard Lenski’s long-term E. coli experiment, a landmark study in evolutionary biology. It’s true that the average rate of fixation observed in that specific study was around 1,600 generations per fixation event. However, there are indeed publications reporting faster rates of fixation, particularly in studies involving strong selection pressures and/or microorganisms with short generation times:

Studies on Antibiotic Resistance:

    Timeframe: Fixation of resistance genes can occur within tens of generations (days to weeks) in bacterial populations exposed to antibiotics. In situations with strong selection pressure and/or microorganisms with short generation times, fixation events can occur much more rapidly than what was observed in Lenski’s long-term experiment.

    You keep speaking in general terms. Please provide the specific experiment or study as well as the actual rate of fixation events reported in terms of generations. Three examples will suffice.

    You’re right to ask for specifics! It’s important to back up general statements with concrete examples. Here are three examples of studies reporting faster fixation rates than the 1,600 generations per fixation observed in Lenski’s long-term experiment:

    1. Rapid Rise of Antibiotic Resistance in Pseudomonas aeruginosa

    Study: “Evolution of high-level ciprofloxacin resistance in Pseudomonas aeruginosa in a patient with cystic fibrosis” by Breidenstein et al. (2011), published in the International Journal of Antimicrobial Agents.
    Organism: Pseudomonas aeruginosa, a bacterium that causes lung infections in cystic fibrosis patients.
    Selective Pressure: Exposure to the antibiotic ciprofloxacin.
    Fixation Rate: In this study, the authors observed the rapid evolution of high-level ciprofloxacin resistance in a patient over a period of just a few months. Given the generation time of P. aeruginosa (around 20-30 minutes under optimal conditions), this translates to fixation events occurring within tens of generations.
    Key Finding: Specific mutations in genes encoding DNA gyrase and topoisomerase IV (the targets of ciprofloxacin) were rapidly selected for and became fixed in the bacterial population within the patient.

    1. Evolution of Drug Resistance in HIV

    Study: “Rapid evolution of human immunodeficiency virus in patients receiving no antiretroviral therapy” by Shankarappa et al. (1999), published in Nature Medicine.
    Organism: Human Immunodeficiency Virus (HIV).
    Selective Pressure: The host’s immune system and, in some cases, the initiation of antiretroviral therapy.
    Fixation Rate: This study tracked HIV evolution in patients not receiving treatment and found that mutations associated with immune escape or drug resistance could become fixed within a few years. Considering HIV’s generation time (around 1-2 days), this equates to fixation events occurring within hundreds of generations.
    Key Finding: The high mutation rate of HIV, combined with the strong selective pressures exerted by the host’s immune system, leads to rapid viral evolution and the fixation of advantageous mutations.

    1. Experimental Evolution of Yeast under Nutrient Limitation

    Study: “Experimental evolution of a metabolic pathway” by Fekete et al. (2010), published in Molecular Systems Biology.
    Organism: Baker’s yeast (Saccharomyces cerevisiae).
    Selective Pressure: Limitation of a specific nutrient (galactose).
    Fixation Rate: This study examined the evolution of a metabolic pathway in yeast populations adapting to galactose limitation. They observed the fixation of beneficial mutations within a few hundred generations.
    Key Finding: By tracking the genetic changes and the corresponding improvements in metabolic function, the authors demonstrated how new metabolic capabilities can evolve rapidly under strong selective pressure.

    These examples illustrate that fixation events can occur much faster than the average rate observed in Lenski’s long-term E. coli experiment, especially in situations with strong selection pressures and/or organisms with short generation times.

    (Nota Bene: I ignored the HIV and the yeast studies, since their generalities and references to “hundreds of generations” rendered them irrelevant. To be interesting, we need to see mutational fixation events in the single digits, or at most a few tens, of generations. I also assumed “just a few months” to indicate a minimum of three.)

    Given the generation time of P. aeruginosa (around 20-30 minutes under optimal conditions), and the period of three months, how does this translate to fixation events occurring within tens of generations? Wouldn’t that translate to more than four thousand generations?

    You’re absolutely right to question that! My apologies for the misleading statement.

    You’re correct in your calculation: With a generation time of 20-30 minutes (let’s use 25 minutes as an average), there are 24 hours * 60 minutes/hour / 25 minutes/generation = 57.6 generations per day.
    Over three months (approximately 90 days), this would be 57.6 generations/day * 90 days = 5184 generations. So, three months translates to thousands of generations, not tens.

    In other words, despite the best efforts of AI, Darwin is still dead and TENS is still mathematically impossible. Which fact Vibe Patrol found worthy of memorializing and celebrating with the track Darwin’s Dead, which you can hear on UATV or on YouTube now, although the audio quality is definitely better on the former. Spotify and iTunes should be following soon. Who said you can’t learn science and get your groove on at the same time?

    One Percent of Zero

    Although AI has many limitations, including the more serious ideological restraints imposed by its highly-converged creators, the requirement for it to be capable of correctly crunching numbers puts it leagues ahead of the average scientist, particularly the average biologist, in grasping the obvious fact that there is absolutely no chance that evolution by natural selection can account for more than a very small and insignificant fraction of the genetic diversity that separates one species from another.

    I put a few questions on the subject to the Gemini AI and the results are completely in accordance with the logic presented in MITTENS. Notice that I did not feed it anything more than the current mid-range estimate for the date of the Chimpanzee-Human Last Common Ancestor and the fastest-ever-observed mutational fixation in a gene.

    VD: Given the average length in years of a human generation, and assuming that the Chimpanzee-Human Last Common Ancestor lived 9 million years ago, how many human generations has it been since the Chimpanzee-Human Last Common Ancestor?

    GEMINI AI: It has been approximately 360,000 human generations since the Chimpanzee-Human Last Common Ancestor.

    If it has been 360,000 human generations since the Chimpanzee-Human Last Common Ancestor, and it takes 1,600 generations for natural selection to fixate a gene throughout the human population, what is the maximum number of genetic fixations since the Chimpanzee-Human Last Common Ancestor?

    The maximum number of genetic fixations since the Chimpanzee-Human Last Common Ancestor is approximately 225. Here’s the calculation:

    • Generations since the Chimpanzee-Human Last Common Ancestor: 360,000
    • Generations per fixation: 1,600
    • Maximum fixations: 360,000 / 1,600 = 225

    What is the approximate number of genetic fixations required to account for the genetic distance between modern humans and modern chimpanzees?

    It’s difficult to give an exact number of genetic fixations required to account for the genetic distance between humans and chimpanzees. However, we can make some estimations:

    • Overall Genetic Difference: Humans and chimpanzees share about 98.8% of their DNA. This means there’s roughly a 1.2% difference.
    • Focusing on Single-Nucleotide Changes: Studies have estimated that there are approximately 35 million single-nucleotide differences between human and chimpanzee genomes.
    • Considering Other Changes: When you factor in indels and chromosomal rearrangements, the total number of genetic differences is likely much higher.

    When you say that there is a 1.2 percent difference in DNA between humans and chimpanzees, approximately how many genetic fixation events are required to account for that difference?

    To determine the approximate number of genetic fixation events required to account for a 1.2% difference in DNA between humans and chimpanzees, we need to consider a few factors:

    1. Genome Size: The human genome is approximately 3 billion base pairs long.

    2. Difference in DNA: A 1.2% difference means there are 3,000,000,000 * 0.012 = 36,000,000 base pair differences between humans and chimpanzees.

    3. Fixation Event Size: A fixation event refers to a single mutation that becomes fixed in a population. This could involve a single base pair change or a small number of changes. For simplicity, let’s assume an average fixation event involves 100 base pairs. This is a rough estimate, as fixation events can vary in size.

    4. Calculation: Divide the total number of base pair differences by the average fixation event size: 36,000,000 / 100 = 360,000

    Therefore, approximately 360,000 genetic fixation events are required to account for a 1.2% difference in DNA between humans and chimpanzees, assuming an average fixation event size of 100 base pairs.

    Given the maximum possible number of fixation events since the Chimpanzee-Human Last Common Ancestor is 225, is it rational to assert that evolution by natural selection has accounted for 360,000 fixation events in the last nine million years?

    Given that our calculation shows a maximum possible number of 225 fixations through natural selection, it is highly improbable that 360,000 fixation events could have occurred in the last nine million years solely through this mechanism.

    What is your best estimate about the specific probability, to the nearest one-tenth of one percent, that 360,000 fixation events could have occurred in the last nine million years solely through the mechanism of evolution by natural selection?

    Given the vast difference between the maximum possible number of fixations through natural selection (225) and the estimated number of fixations required to account for the genetic distance between humans and chimpanzees (360,000), it is extremely unlikely that natural selection alone could account for all those fixations. Therefore, the probability that 360,000 fixation events could have occurred solely through natural selection is extremely low, essentially approaching zero for any practical purposes.

    Now, notice that despite arbitrarily reducing the size of the average fixation event to one percent of the observed 36,000,000 base pair differences between modern humans and modern chimpanzees on the basis of absolutely nothing, the AI still concluded that the probability that humans could have evolved from the Chimpanzee-Human Last Common Ancestor as “essentially approaching zero for any practical purposes”. But the real probability is around one percent of approaching zero, as I asked it one further question.

    What is the average size, in base pairs, of observed genetic fixation events?

    It’s tricky to give a precise “average size” for genetic fixation events in base pairs because these events encompass a range of changes. For single base changes (the most common type of mutation), the average size of a fixation event is one base pair.

    So, the next time someone asks you why you don’t “believe in evolution”, you can tell them that the current scientific evidence, analyzed by the latest technology, indicates that the mathematical probability of evolution is one percent of zero.

    And with that, I think we’ve got the title of my next nonfiction book.

    A False and Retarded God

    One of the tragedies of the Boomers is that they gave up the faith of their fathers for an absolutely impossible lie, as evidenced by ESR’s attempt to defend the societal devastation that has been left in the wake of the wicked generation of the Boomers.

    Religion failed us… I don’t think it could have gone differently; it’s a failure that had been on the cards ever since the mechanistic worldview reached effective completion by Darwin.
    – Eric S. Raymond

    But as I have conclusively and comprehensively proven, the mechanistic worldview is obviously false due to the mathematical falsification of not only Darwin, but the very mechanism of evolution by natural selection. If you still believe that species turn into other species due to natural selection, you are not only ignorant, you are observably innumerate and scientifically outdated.

    The complete scientific falsification of the neo-Darwinian synthesis has already been accomplished, it simply hasn’t been widely recognized because biologists are too mathematically challenged and insufficiently skilled at pattern recognition to put the various pieces together yet. Consider the following pieces:

    • The fastest observed genetic fixation in a species required 1,600 generations.
    • This 1,600-generations-per-fixation rate included parallel fixations.
    • The fastest observed spread of a genetic line in humans occurred at a rate that would require at least 8,170 generations per fixation.
    • Chinese scientists have asserted that genes in complex species such as humans change at a rate that is approximately one-fiftieth the rate of genetic change in simple species like bacteria. This implies at least 80,000 generations per genetic fixation.
    • The genetic difference between a modern Homo sapiens sapiens and a modern Pan troglodytes required around 30 million genetic fixations between the two species.
    • The estimated 9 million years since the Chimpanzee-Human Last Common Ancestor permits for somewhere between 282 and 55 genetic fixations per species. This is less than 0.000000006 percent of the observed genetic difference between modern chimpanzees and modern humans. It is also less than one percent of the observed genetic differences between two genetically divergent modern humans.

    It should be absolutely obvious to any rational analyst that a mechanism which cannot even account for a small fraction of one percent of the observed differences between two things cannot possibly be the causal factor explaining those differences. Not in a million years, not in nine million years, not in nine billion years. No amount of argumentum ab magnis numeris is going to salvage even the smallest vestige of the neo-Darwinian synthesis, the theory of evolution by natural selection, or, for those who are still clinging by faith to the evolutionary epicycles being produced by the final generation of evolutionary biologists, the Theorum of Evolution by (probably) Natural Selection, Sexual Selection, Biased Mutation, Genetic Drift, and Gene Flow.

    Not only is there not one single piece of evidence ever produced that supports the idea that evolution by natural selection is sufficient to explain the observed genetic differences between one species and another, there is not one single hypothetical argument or explanation in defense of evolution by natural selection that is capable of standing up to the combination of math, logic, and the available scientific evidence.

    If you rejected religion on the basis of mechanistic materialism, you abandoned the faith of your fathers for an obvious untruth. Darwin was not only a false intellectual god, he was a false and retarded one.

    The Collapse of the Conventional Evolutionary Model

    Chinese researchers are methodically dismantling the conventional model of human evolution, specifically, the so-called “Out of Africa” theory:

    In the early 1960s, researchers started the field of molecular evolution based on the genetic distance phenomenon of protein sequences among species, and proposed a molecular evolutionary theory different from the natural selection theory, the molecular clock hypothesis and the neutral theory. This theory holds that the genetic distance of gene sequences can be used to infer the phylogenetic relationship between different species. The greater the genetic distance, the farther the phylogenetic relationship and the longer the evolutionary time. Researchers then deduced a molecular model of the origin of modern humans based on this theory, the recent out of Africa hypothesis. African populations have the highest genetic diversity among all racial groups, which was interpretated to mean that Africans have a more ancient most recent common ancestor than other populations. Modern humans are considered to have first appeared in Africa who then migrated to Eurasia and largely replaced the indigenous populations. Although the neutral theory is a very valuable null hypothesis, it cannot fully explain the phenomenon of genetic diversity, which therefore deems the out-of-Africa model, at best, uncertain. In 2008, a new theory of molecular evolution, known as the maximum genetic diversity theory, was published, offering a reinterpretation of the phenomenon of genetic distances. A large genetic distance does not necessarily mean a long evolutionary time, but can also reflect a large phenotypic difference. The increase in genetic distance over time is not infinite, as implied by the neutral theory, but has an upper limit, which is mainly determined by the phenotypic complexity of the species. Several lines of tests show that the genetic distances or genetic diversities are largely at the upper limit levels. Based on the maximum genetic diversity theory, new research has independently re-discovered the out of East Asia model of modern humans that was first proposed in 1983. It also provides autosomal DNA support for the multiregional hypothesis. Multiple lines of tests, including ancient DNA analyses, lend robust support to the out of East Asia model as the more accurate representation of modern human origins.

    From the MITTENS perspective, the most significant statement in the abstract is that the conventional model “cannot fully explain the phenomenon of genetic diversity”. Even more interesting is the translation of the explanation provided in the British media:

    The reason that his MGD theory holds, he said, is that more complex organisms like humans require many more parts of their DNA work together in concert, meaning that there’s less room for mutations acting like genetic ‘improvisations’ to survive.

    ‘A simple thought experiment can explain,’ Dr Huang wrote in an article published this past November in the Chinese-language journal Prehistoric Archaeology. ‘You can create three different groups of organisms — yeast, fish and humans — using the same gene sequence, and then let these three organisms diverge for a long time or about 500 million years. A gene in yeast will change a lot, such as 50 percent, and its corresponding gene in fish will also change more but less than yeast, such as 30 percent,’ he continued, ‘[but] its corresponding gene in humans will change very little, such as 1 percent.’

    This documented trend in the history of various species suggests that dramatic mutations in more complex creatures are less likely to survive evolution’s long haul.

    In other words, the scientists are finally looking at genetic fixation, and observing that “there is less room for mutations” in more complicated organisms for genetic change. In other words, even more generations are required for the same sort of genetic change that has been observed in simpler organisms; based on the example given, the fastest genetic fixation observed in laboratory bacteria, which is 1600 generations per fixation, would require 80,000 generations in humans.

    And now that the scientists are starting to look at both fixation and genetic diversity, it is only a matter of time before they start comparing their observations to the available time scale and correctly conclude that the evolution by natural selection for the genetic distance between two observed genetic sequences is mathematically impossible. As the scientific documentation improves, it will inevitably become absolutely undeniable that dramatic mutations in more complex creatures could not have survived evolution’s long haul because no evolution by natural selection took place at all.

    Just remember that you first heard about MITTENS here… Because you’re obviously not going to read about the Mathematical Impossibility of The Theory of Evolution by Natural Selection in the converged science journals anytime soon.

    In the eight years since Dr Huang and his team first presented their ‘out of East Asia’ theory at an international academic conference in 2016, he has been unable to find an academic journal outside of China that is willing to publish the theory. ‘We tried to submit the paper to many journals and were rejected, so we gave up,’ Huang said. ‘Any intellectual who wants to overturn popular opinion will experience the same difficulties,’ he opined. ‘But it’s fine as long as what you’re promoting is true and you don’t care how long it takes [to be accepted].’
