Most students of human sexuality agree on the fundamental principles of human sexual development duck book. The story goes something like this: a man and a woman meet and assess their reproductive potential duck rabbit book. Everyone has a different program is looking for young , health , fertility, virginity and fidelity, while it is the pursuit of wealth duck book, status, health and the likelihood that remained to help to raise children .

Once each decide to take a risk on his counterpart duck book, began to practice monogamy and found a nuclear family. After that, he is more concerned if she was sexually far as she is concerned so far emotionally duck rabbit book.

It seems very narrow minded and rude duck book. But familiar. The classical understanding of what constitutes "normal" human sexuality is impressive critical and normative ( significant increase human misery ) duck book. Most researchers who developed this " standard narrative " of human sexual development is a product of the relatively repressive contemporary culture duck rabbit book. Naturally, it is difficult for them to divorce their full intellectual activities on their own cultural contexts.

However duck book, some people try .

Christopher Ryan and Cecilia JETSAM refute this standard story in his book Sex at Dawn , and although their arguments are not perfect duck book, are useful for anyone who is frustrated by the baby - focus duck book, gender stereotypes duck rabbit book, hetero -centric, war - the - standard tilt sex story I described above. His most important (and lighter) , the conclusion is that the standard story is very wrong.

Some of his evidence is quite interesting duck rabbit book :

We have the same amount of genetic similarity bonbons ( who have sex all the time for a surprising variety of reasons) and chimpanzees ( who fight a lot duck book, most of the time ) duck rabbit book, so it's crazy that researchers insist yet we more like chimpanzees than we are like bonbons.

People living in small groups duck book, feeding and do not care to store food ( as the first human beings seem to have done) have both an immediate impact and relevance of developments in the implementation of a culture that share preferences , and punishes not share (" fierce " egalitarianism ) duck rabbit book, why would this include sex ? Actually duck book, in many contemporary societies of this type, the exchange does not include exchange sex.

Animal species that are monogamous background engage in sexual activity rarely , and limited to times when it is more likely to lead to procreation duck book. Species that have sex regularly and enthusiasm are those who are not monogamous more background duck rabbit book. There is no reason to assume that apparently monogamous but really interested in having a lot of sex duck book, humans are the only species that varies from this model?

Genitals humans have certain anatomical features of interest duck book. For example , sports a very unusual penis duck rabbit book, which has a gland at the end which acts as a suction machine penis during intercourse - in - vagina. If the sperm of another person is already in the woman's vagina , this suction away from your cervix duck book, thus paving the way for the next ejaculation. This anatomical peculiarity lends credence to the idea that the male sperm play in a woman's vagina duck rabbit book. And if the sperm is competed duck book, the rest of us can have sex instead of fighting .

As expected, the book is also on the wider prehistoric human life - and a critical look at how modern scientists do their work in the human past duck soup book. Ryan and pressure on other researchers assumptions is refreshing and interesting. When talking about matriarchy duck book, for example:

" As often happens in trying to understand and discuss other cultures, stumbles specialists writing. When they say they have never found a" true matriarchy duck soup book, "these anthropologists believe patriarchy are imagining a picture, vision which ignores the different ways men and women perceive and exercise power duck book. " (Page 133)

I would say that a statement like " the different ways males and females conceptualize and exercise power duck book" is problematic as well - this is a pretty radical generalization , especially when trying to be inclusive of all human cultures through time. But surely , if Ryan JETSAM analysis and demonstrates sufficiently influential duck soup book, thoughtful and thorough review of the help you examine your assumptions too duck book.

There are other significant challenges JETSAM Ryan and presentation. Particularly one that frustrates me is that most of their attention is focused on what might be called plain vanilla sex right .

This is probably because many of their arguments are rooted in evolutionary biology , a field that has to do with the circumstances, actions and events leading to procreation. However , also based in anthropology and archeology duck soup book, and the work of evolutionary theorists who postulate that cooperation is just as important in evolution as it is the competition factor duck book.

And it seemed surprising to me that there is so little in the book on homosexuality in general or heterosexual acts non - specific procreation. After all duck book, the authors are mostly related to the question of how humans have developed our propensity to engage in sexual activity , you absolutely can not lead to procreation duck soup book. I think they have more to say about the strange way we are.
