Some evidence that life may have originated at least 4.1 billion years ago

For some reason I missed this paper published last November in Proc. Nat. Acad. Sci. USA by Elizabeth Bell et al. , and it doesn’t seem to have been given a lot of attention by the press. That may be because its conclusions are questionable, and based on a very small sample. But if they’re right, it’s a […]

Tiny foxes on the Channel Islands lack not only mass, but also genetic variation and fear of humans

On the Channel Islands, 12-70 miles (20-113 km) off the Pacific coast of southern California, live six subspecies of the Channel Island Fox (Urocyon littoralis), a dwarf species that is a close relative of the gray fox living on the mainland (U. cineroargenteus). Genetic data suggest that these foxes have been isolated from the mainland species for about 9000 […]

Don McLeroy responds to the evidence for whale evolution

The other day I put up a post showing a video by Jon Peters about the evidence for the evolution of whales. That’s one of the great stories of evolution, and is copiously documented with evidence from many areas: the fossil record, genetics, embryology, vestigial organs, and so on. (The reptile—>mammal transition is equally well […]

Rick Harrison died

I was shocked to learn this morning that Rick Harrison, an evolutionary biologist at Cornell, died at 70. He had been treated for a form of cancer a while back, but that was a long time ago, and I assumed he was okay. I’m not sure if that caused his very untimely death (he was a […]

Evidence for evolution: whales

After my CfI lecture in Portland, I met reader Jon Peters, who told me he’d made and videotaped an entire lecture on the evidence for evolution—using only whales and other cetaceans as examples. Some of the material is from WEIT, and I must have given permission for that, though I can’t recall. I may have […]

The newest tree of life: many new groups (all bacteria), some cryptic and enigmatic

We’ve known for a while that there are three great divisions in the tree of life: the Eukaryotes (organisms with “true” cells having a membrane-enclosed nucleus, organelles, and a cell membrane); Eubacteria (“true” bacteria); and Archaea (prokaryotes like Eubacteria, but with genes and biochemistry more closely related to those of Eukaryotes than to Eubacteria). Archaea […]

Templeton wastes $11 million in attempt to change evolutionary biology

For some time, a group of biologists have been promoting the idea that the Modern Synthetic Theory of Evolution (which they call “Standard Evolutionary Theory,” or SET) is incomplete in major ways, and needs a reboot. Their main contention is that the SET is too “gene-centric”, and ignores environmental factors—like non-genetic developmental plasticity, epigenetic modification,  and ‘niche […]

Vestigial traits in humans

Here’s a new video from Vox that demonstrates several vestigial traits in humans. Most of these are in WEIT, but this is a great short video to show students.  I don’t have a palmaris longis on either arm, but I can wiggle my ears. Still, I didn’t know that you can detect futile attempts to […]

Lego Beagle Project passes threshold, now in review for commercial production

Reader Mark R. informed me, to my delight, that Luis Peña’s H.M.S. Beagle Lego kit project announced a year ago February (see here and here), has reached its goal of 10,000 votes and is now at this stage: It’s being reviewed by Lego, and, if approved, it will be made into a commercial kit and sold in stores. […]

The “Angry Cat Man” talks to high-school biology students

I spent an hour this morning talking about Why Evolution is True with two classes of advanced biology students from the University of Chicago’s Lab School. It was a great pleasure to interact with such a bright and interested group of kids, and they had lots of good questions. I won’t go into details, but two things […]
