When I first saw today’s Google Doodle, with the initial animation of a goose nurturing its young, I thought it must be Konrad Lorenz’s birthday. But then the cheetahs and rabbits appeared, and I knew Lorenz didn’t study those. Then I had my “aha” moment: it’s Mother’s Day. What I like about the Doodle is […]

Here’s a short scientific report (yesterday’s didn’t inspire much enthusiasm)—short because much of the paleontology is beyond my expertise, as the paper consists largely of describing features I’m not familiar with. But this new paper in Nature by Min Wang et al. (link and reference below) is quite important, for it describes what appears to be the earliest […]
The kin selection argument continues, with those denying its importance holding firm. They’re wrong.
In 2010, Martin Nowak, Corina Tarnita, and E. O. Wilson wrote a paper in Nature (reference and link below) arguing that “kin selection,” selection based on relatedness (shared alleles among nestmates) was not—as had long been maintained—a key factor in the evolution of “eusocial” insects. (Those are species in which there are nonreproductive “castes” of workers, […]
Five days ago I wrote about the new Nature paper revealing the “dino-bat” fossil Yi qi, a bizarre species of theropod that had feathers but also membranous wings like a bat—and a special new bone, evolved from the wrist, that supported its wing. It isn’t clear whether this creature could fly, but it surely could […]
Simon Conway Morris’s new book once again claims that the evolution of human-like creatures was inevitable. He’s wrong.
Paleontologist Simon Conway Morris has a new book on science coming out, coincidentally, on the same day as mine, and I’m sure that his has religious overtones. The book is called Runes of Evolution: How the Universe Became Self Aware, and, predictably, is published by Templeton Press. Templeton simply laps up books like this. Here’s part of the publisher’s […]
A reader who doesn’t want to be identified wrote in with some information about how Mormons regard evolution (hint: not favorably). I’ll start with his/her “deconversion” story, which is short but emphasizes again the effectiveness of critiques of religion and paeans to reason on drawing people away from superstition. I was raised a Mormon, but became an apostate […]
The evolution of flight in birds must have involved many dead ends, including all those dinosaurs with feathers that never evolved to the flying or gliding stage, or even the flying lineages that went extinct—like all dinosaurs except the single lineage that produced modern birds—when the asteroid whacked us at the end of the Cretaceous. A just-discovered species of dinosaur, described […]
Several readers sent me a link to a piece by Bob Trivers called “Vignettes of famous evolutionary biologists, large and small” (Trivers is of course also a famous evolutionary biologist.) His essay is at the Unz Review, whatever that is, so I would have missed it. Anybody who knows Bob, as I do, also knows that he […]
UPDATE: I’m a real dummy; I failed to check the dates of any of these items and a eagle-eyed reader noted that they’re all from 2011! I should have seen that from the dates on the Science paper, if not the links. Oh well, it’s still interesting stuff. ******* A paper in Science by Ryan McKellar […]
David Sloan Wilson tells the BBC that the evolution of altruism in humans is “solved”: it’s group selection (of course)
Reader Tony from the UK called my attention to yesterday’s “Start the Week” program on BBC Radio 4, which featured the evolutionary biologist David Sloan Wilson discussing the evolution of human altruism with host Tom Sutcliffe. (Click the screenshot below to go to the page, then press the arrow at lower left on that page. […]
