Cat Evolution Nailed Down...
This article in the NY Times about Cat Evolution is great! It's good to see the "paper of record" give such a strong write-up on solid science.
The part I found most interesting was that the common housecat most likely sprang from a "New World" lineage that back-migrated to Asia. I don't know why, but I've apparently always had this image of the Bering land bridge as being a one-way deal, and that's just silly, since there's no bar to moving both ways. I've just never heard of another species migrating from the Americas back to Eurasia like this.
