An ocean liner cannot turn round on a sixpence. Neither can human nature spin itself away from hundreds of millions of years of evolution. Humans are a bundle of pleistocene instincts dressed by Marks & Spencer with some clever gadgetry to hand.
Robert Winston (http://en.wikipedia.org/wiki/Robert_Winston) expertly dissects the deep human motivations that are really in the driving seat. He asks whether these deep instincts are sweetly compatible with the modern technological world that we have built only in the blink of an eye set against evolutionary history. Published in 2002.
