Nature is having a celebration: Darwin 200 (although the 200th anniversary of the great man’s birth isn’t until next February – perhaps Nature is making a point about embryos here). There are a lot of good articles on evolution-related issues, but the one that is most likely to catch the eye of the SF reader is “Let’s Make a Mammoth”. There’s lots of serious biology, and also more about elephant genitals than you probably wanted to know.

Update: And with remarkable timing a team at Penn State announces that they have just completed the first successful sequencing of the woolly mammoth genome.
