UK Kirkus Review » In this gripping accompaniment to the BBC television series of the same name, Robert Winston delves into the inconsistencies so apparent in much of human existence - our irrational decisions, beliefs, urges and interests - and shows that our genetic baggage affects our psychology much as our ape ancestors influence our physical features. The unpredictability of human behaviour is dissected in terms of many influences - instinctive, physiological, rational and emotional and, inevitably, the awesomely pervasive influence of sex. Fertility expert, politician, television presenter and peer of the realm, the incomparable Professor Winston needs little introduction. He writes very much in the way he presents his TV series, so we do get the occasional patronising 'pity about the ladies', and a distinctly conventional medical view of childbirth, along with some contentious discussions of the origins of male sexual jealousy and rape. Winston seems to be one of those media personalities people either love or loathe, but by and large most readers should find the host of intriguing facts more than compensates for any irritations. Winston is certainly game - having his testosterone levels measured during the World Cup, willingly sniffing T-shirts slept in by young female students and engaging in rock climbing despite being frozen with terror. His sound bites are impeccable - 'for modern humans, mating is a bit like playing chess while your opponent holds a gun to your head' - and his analyses of various viewpoints on just why humans behave as they do are generally intelligent and balanced. He discusses, among much else, our tendency to act first and think second; the genetic basis of fear; the evolutionary benefits of risk-taking; a biological basis for violence, and why girls are nicer than boys and men 'programmed to behave badly'. We learn about co-operation and altruism, cheating, empathy, fairness and guilt, en route to conclusions about morality and spirituality. Eminently readable, completely fascinating and undoubtedly another of Winston's media triumphs. (Kirkus UK)
