Because biologists can’t math, and because the “I Fucking Love Science” crowd are retards, they also can’t grasp the way in which the Law of Large Numbers and the Bernoulli Barrier completely rule out their retreat to parallel fixation based on neutral mutations, as Grok did when a reader confronted it with MITTENS and the Moran model.
No meaningful “time to convert” calculation exists here, as fixation isn’t sequential or rate-limited by selection costs.
- Available time: ~6–7 million years since human-chimp last common ancestor.
- Generations: Assuming ~25–30 year human-like generation time, ~200,000–300,000 generations.
- Years: The divergence accumulated gradually over those ~6–7 million years via mostly neutral processes + some selection.
Models easily account for ~20 million lineage-specific fixes without issue.
This is an unbelievably and obviously stupid argument, but it is nevertheless the retreat of choice for those who avoid reading the book and have no idea what a Bernoulli is. And, of course, they don’t do the math, which doesn’t actually work, but because there are considerably more neutral mutations than beneficial ones, it doesn’t work less, which apparently is good enough for retards.
So Athos and I kicked around a few ways to dumb things down sufficiently for them, and when we targeted an 85-IQ range, we finally landed on an explanation that should be able to penetrate their feeble little minds.
The short version: neutral processes + parallel fixation = total species death in 2-3 centuries. Therefore, it cannot be a viable explanation for the 20,000,000 post-CHLCA fixations over the last 6-7 million years.
The long version: When confronted with the mathematical impossibility of natural selection producing 20 million genetic fixations in 202,500 generations, defenders of neo-Darwinian evolution often retreat to “neutral drift”—the claim that mutations spread through populations by random chance rather than selective advantage. This is what they mean when they invoke “mostly neutral processes operating in parallel.” The appeal is obvious: if drift doesn’t require beneficial mutations, perhaps it can escape the reproductive ceiling that limits how many mutations selection can push through a population simultaneously.
Now, there are obvious problems with this retreat. First, Darwin has now been entirely abandoned. Second, it doesn’t actually exist, because Kimura’s model is just a statistical abstraction. But third, and most important, is the fatal flaw that stems from their complete failure to understand what their retreat from selection necessarily requires.
If you ignore natural selection to avoid the reproductive ceiling, then you turn it off for all mutations—including harmful ones. Under pure drift, a harmful mutation has exactly the same probability of spreading through the population as a neutral one. Since 75% of all mutations are harmful, the genome accumulates damaging mutations three times faster than it accumulates neutral ones. Selection, which normally removes these harmful mutations, has been switched off by hypothesis.
The mathematics are straightforward from this point. At observed mutation rates and population sizes, the drift model fixes roughly 7.6 harmful mutations per actual generation. Using standard estimates for the damage caused by each mutation, collapse occurs in 9 generations—about 225 years. The drift model requires 7.5 million years to deliver its promised neutral fixations, but it destroys the genome in between 225 and 2250 years. The proposed drift model kills off the entire proto-human race thousands of times faster than it can produce the observed changes in the modern human genome.
The defender of Neo-Darwinian who turns to drift faces an inescapable dilemma. Either selection is operating—in which case the reproductive ceiling applies and parallel fixation fails—or selection is not operating, in which case harmful mutations accumulate, the genome degenerates, and the species goes extinct. You cannot turn selection off for neutral mutations while keeping it on for harmful ones.
The Bernoulli Barrier closes the door with a mathematical proof. The Drift Deathmarch closes it with a corpse. Some people need to see the corpse. You can’t drift your way to a human brain. You can only drift your way to a corpse.
