These two researchers explore the nature of human mating strategies, particularly in the context of how other species seek and hold on to mates. According to the two authors, behavioral and biological evidence demonstrates very clearly that the inclination towards multiple mates is natural whereas monogamy is not.
They make it clear in the very beginning, however, that this is an entirely separate issue from whether or not monogamy is not possible or even desirable a fact lost on some who have read the book. Rather, the book explores the nature of that behavioral and biological evidence and then what that means for us.
As far as evidence from animal behavior goes, the DNA fingerprinting technology used in courtrooms is now being used by biologists to trace parenthood in animals resulting in some startling discoveries. Even among species previously believed to be monogamous, cheating on mates is the rule for both sexes.
For example, in birds which were assumed to be monogamous, researchers have found that between 10% and 40% of all chicks were fathered by males who were not the mother's social mate.
the book explores the nature of that behavioral and biological evidence and then what that means for us.
Further research has shown that, contrary to popular assumptions, females are just as likely as males to engage in extra-pair mating. The methods used by the two sexes differ, but the basic reason is the same: evolution.
Both males and females want to be sure that they produce the best possible offspring. But because of their different roles, they must adopt different strategies.
For the males, their role is providing sperm and sperm is cheap. A male can produce lots and lots with very little cost, so it makes sense to spread it around as much as possible. Males, then, essentially play the lottery:
they try to mate as often as possible with as many females as possible in the hopes of producing as many offspring as possible. With luck, a few of them will do really well and continue the genetic line.
