I’m just back to my hotel after my Darwin Day talk–a fine, big crowd showed up that included at least a few fellow science bloggers (Bora and Reed, to name two). And if you can handle…just…one…more…wafer-thin Darwin-related experience, please check out my essay, “Darwin Evolving” in the new issue of Time. In honor of his birthday, I take a look at Darwin’s legacy, and the new directions evolutionary biology is taking today.

“We can dimly foresee that there will be a considerable revolution in natural history,” he wrote at the end of On the Origin of Species. He saw his work not as the end of biology but as a beginning.

Photographer Justine Cooper has taken a haunting series of photographs behind the scenes at the American Museum of Natural History. Seed Magazine has posted a slideshow of her work, and I’ve written an accompanying essay on the hidden world that lies behind the dioramas. Check it out.

Okay, you’re approaching Darwin saturation, I know. But how about Darwin’s impact on the English language? The Oxford English Dictionary credits him with the first use of 144 words. Did you know Darwin was the first person to use the word alfalfa in English? Or rodeo? Check out this post from my brother Ben for more. And be sure to read to the end to catch the most surprising neologism of all.

I am hanging out at the airport, having just missed my flight to Raleigh, but free wireless makes it just an extra office. I’ve just read a few complaints on my post about visualizing the tree of life. Some commenters are not pleased that the tree I illustrated the post with does a grave disservice to the overwhelming diversity of the bacterial world. It is certainly true that bacteria (and archaea) are staggeringly diverse. In a spoonful of soil there may be 10,000 species of microbes. By comparison, there are only about 5,000 mammal species. A lot of the diversity in microbes is ancient, since they’ve been around a lot longer than mammals, or even animals.

This week of all things Darwin seemed like a good time to share some news about a project I’ve been working on for the past few months. It’s a book called The Tangled Bank: An Introduction to Evolution.

The inspiration for the book came from a conversation I had last year with the folks at Roberts & Company, a publishing company. They had noticed a growing number of classes about evolution for non-biology-majors, and asked if I’d be interested in writing a textbook for them. I was excited by the prospect of being able to bring together the things I’ve learned and written about over the past few years, as evolutionary biologists have made a string of surprising new advances in understanding the history of life (many of which I’ve written about here at the Loom).
