Some Ethiopian genes look suspiciously like Israeli genes. And the shared genes appear to be 3000 years old. Just about the time a certain Queen of Sheba and her entourage visited a King Solomon, according to an ancient text or two. It's a small thing, but it's very interesting.
Does that mean that we can identify some of Solomon's genes? This is like some kind of weird mash-up of Raiders of the Lost Ark with GATTACA.
