Changing Gears

I just couldn't get into Climbing Mount Improbable. I'll pick it up again later, though. Instead I started reading Jacob's Legacy a few days ago. Very interesting stuff! The author discusses his studies of Jewish genetics and things like tracing claims of Jewish priests back to a single common ancestor some 3000 years ago. Regardless of how much you believe their religion it is still interesting how things like this can be traced through the genes.
