I saw a couple of stories about new work on the gene people are very eager to associate with the ability of humans to create and use language, FOXP2. I haven't had time to read the Nature piece, though, and only this morning saw a piece that seems clear about the news. It's this, by Nicholas Wade in the NYT. Daniel Geschwind of UCLA says about the work of his team that they want “to use FOXP2 as a lever to get a view of the molecular machinery in a biological language circuit.”
Update, 11:00: Here's the Nature new bit on the topic.
