OK, I loved Sykes' book "The Seven Daughters of Eve." So I wanted to read this one as well. Very disappointing. For one thing, I couldn't care less about the mating and reproductive habits of insects. For another, while I understand his wish to clarify things scientifically, I thought some of his opinions about women and homosexuality were pretty outlandish. There were a few interesting things in the book. The parts about Ghengis Khan would be one example.But my biggest issue with the book is that Sykes seems to have gotten way too full of himself and way too focused on "being a writer." Please! Do I really care what the weather was like or what the library looked like when he got idea XYZ? What made the other book so engaging was that he was just telling about the excitement of the discovery process and some of the possibilities for these women who many of us are descended from.
