Heigh Ho, Heigh Ho!

But before going to work I’ll let you know that I’ve finished Mapping Human History. The author’s intention is best summarized by his last sentence: “We are members of a single human family, the products of genetic necessity and chance, borne ceaselessly into an unknown future.“

I learned about Y-chromosome Adam (the common male ancestor of all living men) and learned more about mitochondrial Eve—the common mother of all the living. (There's no biological evidence these two knew each other.) Now I’m curious about the ”Seven daughters of Eve“ thesis that someone came up with.

Anyway, I’m now starting Sophie's World. Got to go.
