Science Breakthrough of the Year: Human Genetic Variation

The new issue of Science only briefly touches on why this is the 2007 breakthrough. There's a short piece by Elizabeth Pennisi and another by Jocelyn Kaiser. There is also a video about halfway down on this page. At least they had a short part on the burgeoning industry of personal genomics. One area that they side-stepped however was all the genetic information we've been getting on population differences, and on genetic ancestry. Again, the whole thing was just too short. The cover photo is of a guy wearing a t-shirt that has the annotated gene-sequence map of human chromosome 1.
