I just noticed that in the new issue of the New Yorker Michael Specter has written an article on the viruses in our genome. I wrote about this research in the New York Times a year ago. I haven’t had a chance to read the article through yet, but I was mortified to come across this line…

Until recently, the earliest available information about the history and the course of human diseases, like smallpox and typhus, came from mummies no more than four thousand years old. Evolution cannot be measured in a time span that short.

For my latest “Dissection” column in Wired, I take a look at the tree of life, and the way it changed dramatically thirty years ago this month. To get a sense of what the tree looks like today, I pointed readers to the wonderful interactive tree of life at the European Molecular Biology Lab. But I didn’t realize until after I finished the column that when you scroll over the branches of the tree, pictures pop up of species at their tips. Most of the pictures are of assorted chains, blobs, and other microbial portraits. But things get more interesting in the animal kingdom. Iz very nice!

Once the writers’ strike is over, anyone in the mood to make a new monster movie might consider this beast, described today in the journal Biology Letters. It’s Jaekelopterus rhenaniae, a “sea scorpion” that lived 390 million years ago. Based on a fossil of its enormous claws was found in Germany, scientists estimate it measured 2.5 meters long. It’s the biggest arthropod yet known, a giant among giants. At this period in the history of life, lots of insects, millipedes, and other sea scorpions grew to science-fiction sizes, possibly thanks to the high levels of oxygen in the atmosphere at the time. Our own ancestors–lobe-fin fish–might well have been the hapless prey of this spineless behemoth.

“This neuron tattoo was done a few months ago. When I was 18, my dad passed away from Lou Gehrig’s, which is a disease of motor neurons that innervate muscles. His battle with neurodegeneration helped me decide on a career in medical research, and I am currently pursuing my PhD in Neuroscience.”–Lindsay

I fell behind on my Friday uploads to the Flickr site. But the tattoos keep coming. We’re up to 97…so if you want to be tattoo #100, email me soon.

The deja vu is hitting hard.

Two years ago a Pennsylvania court was hearing a challenge to introducing intelligent design into a public school in the town of Dover. At the time, I argued that people should look south to understand the stakes of the conflict. Down in Florida the state government seemed to be trying to have it both ways when it came to creationism. The chair of the state House Education Council introduced a bill that would allow students to sue their professors if they didn’t consider intelligent in class. Governor Bush refused to comment on whether intelligent design should be taught in class.
