A quick heads-up: I’ll be talking about the tree of life tomorrow morning on NPR’s Saturday Weekend Edition. The segment will be archived on their “Science Out of the Box” web page. We’ll be talking about everything from animals to mushrooms to the unclassifiable viruses that graft the tree of life into a web.

Update: 12/1 10 am: …or maybe not. As far as I could tell over the breakfast din, the piece didn’t run this morning. I’ll let you know when and if it does.

Update: 12/1 5:30 pm: The piece just ran. I don’t think I made any major gaffes, but fact-check away. Here’s where you can listen online.
