Today I’ve got an article in the New York Times about the report in Nature that starlings can recognize syntax-like patterns in songs, and what that might mean–if anything–for the evolution of language. The blogs have been buzzing about the study since it came out on Wednesday, with the Language Log logging in several complaints about bad science and bad reporting. (Fortunately, they gave me a pass, and I hope not merely because I’m the brother of one of the bloggers there!)
The Loom gathered a bit of dust over the past couple weeks as I grappled with another round of deadlines for work that actually pays the mortgage. Life should now get relaxed enough for more blogging, I hope–starting this evening. And as the articles I’ve been working on come out in the next few weeks, I’ll point you to the links–starting with my recent (brief but free) take on the new fossil of snakes with legs for the New York Times. And speaking of evolutionary transitions, I’m also happy to bring news of a cool new project, called Kosmos: You Are Here. It’s an e-book on the history of life and the universe.
The New York Times, April 25, 2006
Charles Darwin was fascinated by snakes — in particular, by the tiny hip and leg bones nestled inside boa constrictors and other species. They were some of the most striking cases of evolution’s imprint. Snakes descended from walking ancestors, and as they adapted to slithering, their legs dwindled to a few vestiges.
It took more than a century after Darwin’s death for paleontologists to find fossils of snakes with legs. In the last decade, they have found four species. The fourth, known as Najash rionegrini, was unveiled in the April 20 issue of the journal Nature, and it has reignited a debate about how snakes lost their legs.

Tomorrow I’ll be on the radio show Science and Society at 4:20 PM EST. It’s my second time on the show. Last time around we talked about the past six million years of hominid evolution (podcast here). This time we’re hoping to cover just a bit more ground: the past 600 million years of vertebrate evolution. We’ll try to hit on the big innovations that our ancestors acquired after we parted ways with the squishy beasts–such as brains, bones, a smart immune system, and hands and feet. You can listen live here, and the podcast should be available here shortly afterwards. is here. (Scroll down a bit to my segment.)
At the Loom we believe that the path to wisdom runs through the Land of Gross.
We do not show you pictures of worms crawling out of frog noses merely to ruin your lunch. We do not urge you to check out these freaky videos of worms crawling out of frog mouths and fish gills merely to give you something to talk about at the high school cafeteria table tomorrow (Dude, you totally will not believe what I saw…) These images have something profound to say.
