4000 year old human genome from Greenland

There's a nice post over at John Hawk's Weblog on the recent news that a group of researchers sequenced nearly 80% of the genome from a human that lived in Greenland nearly 4000 year ago.  The paper can be read in full online via Nature (PDF). If you're going to read the paper, do check out John's post for his commentary on the open and collaborative nature of this work.
