Do Gentlemen Really Prefer Blondes?: Bodies, Behavior, and Brains--The Science Behind Sex, Love, & Attraction Review

Average Reviews:

(More customer reviews)I picked up this book initially because I wanted to know the answer to the question in the book's title: Do Gentlemen Really Prefer Blondes? (because I do!). The book explained several questions that I had been curious about. Since I am a face man, I was curious to know why certain faces are so irresistible to me. The answer was surprising and yet completely understandable in evolutionary biological terms. An attractive face is a symmetrical face, indicating genetic and developmental health of the individual and therefore his or her attractiveness as a mate. Why is long hair sexy? It's not obvious, but again it's explained by evolution and biology. Can semen in your body from your partner make you happy? Why do men have more casual sex than women? You can say the answer is that they are dogs, but that's not the evolutionary reason. And for you singles: you should know that intercourse with a partner is more satisfying than masturbation. Love makes you blind. It turns out it's not just a saying. What body language do men or women use to let you know that they are interested? This too has to do with the evolution of human behavior.

I learned a surprising amount of evolutionary biology and psychology from this book!

Why Is Sex Fun?: The Evolution Of Human Sexuality (Science Masters) Review

Average Reviews:

(More customer reviews)There is a minor truth-in-advertising issue regarding Why Is Sex Fun?: The Evolution of Human Sexuality, by physiologist Jared Diamond: The title question is never really addressed. The true theme seems to be How Sex Came to be Sex as We Know It. Not that this isn't interesting in its own right, of course. It's just that the original question is worthy of discussion too.
Why is Sex Fun? reads like a lecture series rather than a book. Apparently intended to provide the reader with an overview of the latest thinking on the evolutionary aspects of the subject, this short work includes sections on different sexual (and mate) selection strategies employed by males and females (presumably based on unequal "investments" in the methods of getting one's genes into the next generation); lactation (why milk is produced by females, but not, as a rule, males); how and why humans, almost uniquely, came to engage in engage in recreational sex; the unequal domestic roles played by males and females, particularly in child rearing; female menopause (which is, again, nearly unique to humans); and sexual signaling (Diamond considers penis length in human males to be a prime example, but not necessarily a signal directed at females).
As fascinating as these subjects are, there is much more that is left out. Any full discussion of human sexuality, especially with the high-order concept of "fun" in its presumed abstract, needs to deal with that odd species' whole gamut of non-procreational expression: homosexuality, old-age love, and sex-as-power, for non-inclusive example. But Why is Sex Fun? treats the very large subject of recreational sex only from the "selfish gene" point of view. Even then, there is at least one major methodological criticism: Most evolutionary biologists and evolutionary psychologists go to great lengths to bring out the importance of "ancestral environment". That is, gene-based behavioral tendencies have evolved over a great deal of time, so it doesn't do a lot of good to consider them only from the standpoint of a modern participant. This problem crops up in Diamond's discussion of male hunting strategies. In a modern hunter-gatherer society, men typically go for the "big kill" (a large mammal, for instance), while women are more content to gather roots and so on. Diamond makes the point that the male strategy makes no sense nutritionally, so the answer must be found in differential sexual strategies. However, the possibility is not mentioned that hunting patterns may have evolved when big game was, in fact, rather more plentiful than it is today.
All this is a pity, because we know, from the author's other works (especially the wonderfully told Guns, Germs, and Steel), that he is quite capable of a fully formed presentation. Sex deserves it.
