Mailvox: a new find

GT would like to know what I think about the fossil record in light of this newly announced discovery:

Researchers in China and the UK say they have discovered the fossils of a new type of flying reptile that lived more than 160 million years ago. The find is named Darwinopterus, after famous naturalist Charles Darwin. Experts say it provides the first clear evidence of a controversial type of evolution called modular evolution.

My first thought is that all new fossils should be named after St. Darwin of the Galapagos. I want to see them all named Darwin Darwin Darwinus and anything less would be an insult to a particular agglomeration of atoms that coalesced for a few decades before dispersing more than a century ago. I have to admit, I find the cult of the dead scientist to be tremendously amusing, especially given the way in which this particular dead scientist’s theory has done little more than ride the coattails of Mendel’s for sixty years. But it keeps a number of socially awkward men happily occupied without bothering anyone, and as we know from Keynes, digging holes in the ground stimulates the economy, so it’s all good.

But in answer to the question, there are two ways of looking at this, that of the true believer and that of the skeptic. The true believer, naturally, will point to the discovery and say: “look, one more gap filled!” That’s a perfectly reasonable perspective, and indeed, it fits with the True Belief that given enough time, chance, and government funding, every gap in the fossil record could theoretically be filled. Just do enough digging and eventually there won’t be any room for doubt. At which point, presumably all the evolutionary biologists can go home and spend their days singing songs to St. Darwin since there won’t actually be any need for their so-called science once the bone collection is complete.

The skeptic, on the other hand, notes this interesting sentence in the middle of the piece: “Researchers say that this could be evidence of what they call modular evolution – where natural selection forces a whole series of traits to change rapidly rather than just one.” Given the difficulty evolutionists have had over the last 150 years in demonstrating the ability of natural selection to permanently change even a single trait, this is a significant alteration to the historical theory. I’ve commented before on how a scientific theory in the process of failing requires adding increasingly contorted epicycles and “modular evolution”, like “punctuated equilibrium” sounds very much like one of those things.

Of course, in light of the recent news that paleontologists may not be able to tell baby dinosaurs from distinct species, perhaps the fact that the new discovery has a head and neck just like that of “advanced” pterosaurs, while the rest of the skeleton is identical to that of “primitive” forms indicates that we should assume these are simply three examples of the same species at different ages.


So much for the fossil record

Big dinosaur, little dinosaur, what didn’t begin with E?

Many dinosaurs may be facing a new kind of extinction—a controversial theory suggests as many as a third of all known dinosaur species never existed in the first place. That’s because young dinosaurs didn’t look like Mini-Me versions of their parents, according to new analyses by paleontologists Mark Goodwin, University of California, Berkeley, and Jack Horner, of Montana State University. Instead, like birds and some other living animals, the juveniles went through dramatic physical changes during adulthood.

This means many fossils of young dinosaurs, including T. rex relatives, have been misidentified as unique species, the researchers argue.

Obviously, the jury is still out on this one. But, if it’s demonstrated to be correct, it will be a tremendous blow to TENS. If paleontologists can’t even be relied upon to correctly distinguish between mature and immature examples of the exact same species, this will obviously cast serious doubts on the credibility of the fossil transition sequences between species that they have constructed.

I await with amused interest for the true believers to explain how a complete misreading of a significant portion of the fossil record should not be taken as a reason to doubt any conclusions that were made based on the incorrectly interpreted fossil record.


Revising the revision, again

A Dog Named Flea

Assuredly he lacks the spine
To ascertain the big canine.
Should we encounter in debate
He’ll meet a most odorous fate,
For in taking him down a peg
I have merely to lift my leg
And R. Dawkins will slink away
Wet, and wearing Eau de Day.

It doesn’t matter what the evidence is, evolutionary biologists are happy to change their story to suit. They’ve certainly had enough experience at it:

The story of a critical phase in human evolution may have to be rewritten after the discovery of two remarkable fossils in Kenya that have shed new light on the origins and behaviour of two ancient relatives of Homo sapiens. One of the fossils found near Lake Turkana has shown that two early human species thought to have evolved one from the other actually lived side by side for almost half a million years, redrawing the most widely accepted version of humanity’s family tree.

The discovery means that only one of the two species, known as hominins, can be a direct ancestor of modern human beings, and not both as was previously proposed. While scientists are still confident that Homo erectus, the younger of the two, ultimately gave rise to Homo sapiens, it is now suspected that the older, Homo habilis, was an evolutionary dead end.

Both are likely to have evolved from another, older common ancestor, a missing link that has not yet been found in the fossil record, which lived between two and three million years ago.

It’s probably to be found in the same place as Richard Dawkins’s magic original replicators and the rainbow-maned unicorns of Happy Happy Unicornitopia.

I’ve found the most judicious way to deal with people who ask if I believe in evolution is to respond with a single two-word question: “Which version?” That serves nicely to head off the irrelevant Creationist-ID-God tangent that otherwise tends to pop up, and leads to much more interesting discussions.

“Evolution works like this!”

“I don’t buy it.”

“You ignorant science-hating retard! You probably think the world is flat!”

“No, I just think that your scientific consensus is based on series of false assumptions, unproven postulates and a certain amount of chicanery.”

But 10 out of 10 biologists and geologists agree – hang on – um, okay, actually evolution works like THIS!”

“You do know that a model is only valued based on its predictive abilities… and you’re trying to sell me one that is not only in constant flux but can’t even reliably explain past events, right?”

“What does that have to do with anything?”

“You’ve never done very well on the stock market, have you.”

“No.”

“Didn’t think so.”
