@SavoirFaire: well, if those premises are true, I guess they would suggest that women wouldn’t evolve such signals. But, lo and behold, very many women, and very few men, emit a loud auditory signal informing everyone nearby exactly what they’re doing – that they do so needs some explaining that’s better than “gee, women wouldn’t do that because they’re supposed to be monogamous.” And I doubt many men would dispute, given their “lack of control,” that upon hearing that sound, they at least prepare to have sex themselves. Besides all that, going by your account, evolution ought to have encouraged silent sex, not the raucous variety humans have. That human sexual behavior resembles that of chimpanzees ought not to surprise anyone – the chimpanzee is the closest human relative. In the case of making noise to alert other partners, it resembles many mammals including housecats.
Human beings in agricultural and industrial society are indeed very often serial monogamists, with a remarkable capacity for “cheating” on spouses, which suggests that such serial monogamy is an adaptation to such social pressures in post-hunter-gatherer society (part of the premise of the book, but probably not very disputed), or perhaps some other condition (STDs?). Polygyny probably isn’t very common in pre-agricultural societies – what is surprising that polyandry might be (or might have been, as the case may be). Polygyny, on the other hand, seems common in pastoral societies, or successor societies to pastoral ones (e.g., certain places where there are many oil magnates).
I might agree that female sexuality is more adaptable, but I’m not sure I can agree that women have more control over their sexuality than men in general under “natural” circumstances. There are hordes of problems with this idea. The most obvious is, the only places where women might be close to natural in the way you’re presumably imagining, pre-agricultural societies, are the very places where women have a lot more say about how they have sex – and maybe can pursue they’re own sexual partners in a manner similar to contemporary western men.* The next is that human males in agricultural and industrial societies are skewed towards seeing a childrearing wife as part of his estate, an idea hardly abandoned even in the most socially progressive 21st century societies. It also sounds like it assumes that women for some reason have a lesser urge to have sex than men – that sounds dubious to me. I suspect it’s a generalization based on largely on the behavior of sexually charged, and often sexually deprived, young males who haven’t discovered how to be patient, charming, seductive, or witty yet.
I don’t expect “scientists” to give automatic blanket endorsements of controversial new works, but Sex at Dawn didn’t do much original research at all. It simply synthesizes previous research and theories, and I wasn’t really addressing the book’s conclusions – though the matter I mentioned was used to defend their claims.
* You find this as a trope in literature sometimes, where a subsistence woman in a colonized society comically pursues an explorer sexually. It certainly came up even in relatively recent Hollywood films, like Ace Ventura 2.
