The coelacanth genome has been sequenced, which is good news all around…except that I found a few of the comments in the article announcing it disconcerting. They keep calling it a “living fossil” — and you know what I think of that term — and they keep referring to it as evolving slowly The slowly …

Another feathered dinosaur has been found in China, prompting Ken Ham to dig in his heels and issue denials. Yet another supposed “feathered dinosaur” fossil has come to light, again in China. (Dr. Elizabeth Mitchell, AiG–U.S., reported on another Chinese fossil of a supposed feathered dinosaur in April 2012) Now, one headline described the fossil …

Eugene McCarthy, the author of that crackpot stabilization theory, has discovered my review and is now making a noise on twitter. He’s gone from thanking me profusely for mentioning him, to whining that I stole his figures, to complaining that I don’t understand his theory at all, all in the last 24 hours. But here’s …

It always seems to be the case that there are gaps in the fossil record just where things get interesting — probably with good reason, that forms in transition will be relatively rare. One such gap is the period where insects first emerge and begin to conquer the terrestrial world, a period called the arthropod …

I don’t mind the portrayals of dinosaurs in coitus, but look at those two: did they have to have such lecherous grins? The disturbing thing is that that is the same expression they’d have on their face when they were ripping up a hadrosaur. Being a monkey-faced primate with a dependence on facial expressions really …

If you ever get a chance, spend some time looking at fish muscles in a microscope. Larval zebrafish are perfect; they’re transparent and you can trace all the fibers, so you can see everything. The body musculature of fish is most elegantly organized into repeating blocks of muscle along the length of the animal, each …

A while back, I told you all about this small piece of the biochemistry of the fly eye — the pathways that make the brown and red pigments that color the eye. I left it with a question: if even my abbreviated summary revealed considerable complexity, how could this pathway evolve? Changing anything produces a …

I’ve written about the spectacular phospatized embryos of the Doushantuo formation before. It’s a collection of exceptionally well preserved small multicellular organisms, so well preserved that we can even look at cellular organelles. And they’re pre-Cambrian, as much as 630 million years old. They’ve been interpreted as fossilized embryos for which we have no known …

Look with your puny camera eyes! Some new specimens of Anomalocaris, the spectacular Cambrian predator, have been discovered in South Australia. These fossils exhibit well-preserved eyes, allowing us to see that the bulbous stalked balls on their heads were actually fairly typical compound eyes, like those of modern insects. Anomalocaris eyes from the Emu Bay …

A few weeks ago, PLoS One published a paper on the observation of preserved chitin in 34 million year old cuttlebones. Now the Institute for Creation Research has twisted the science to support their belief that the earth is less than ten thousand years old. It was all so predictable. It’s a game they play, …
