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).
There are perhaps ten million species on Earth, joined together by common ancestry. But even 3000 species are practically impossible to represent on a single evolutionary tree. So how shall we ever see the tree of life (especially if it’s also a web in parts)? That’s the subject of my latest article in tomorrow’s New York Times, “Crunching Data for the Tree of Life.” It’s one of a set of stories the Times is publishing in observation of Darwin’s birthday. Check them all out.
Over at Science, I’m doing a little guest-blogging this months on their Origins blog. My post today is on interplanetary kudzu and other things that NASA can learn from Darwin. Check it out.

In honor of Darwin’s birthday, Forbes publishes a piece by Young-Earth creationist Ken Ham. US News and World Report publishes another piece by another Young-Earth creationist, Henry Morris III.
Sorry guys, but I just can’t find the strength to link to your stunts.
Thanks to Pharyngula and Knight Science Journalism Tracker for spoiling my afternoon. (Huh, that’s funny–I was able to link to them.)
