Purchase options and add-ons
This classic work on the rules of sex -- updated for a new generation -- is still as provocative as the day it was published, providing simple explanations for any and all questions about what happens in the bedroom.
Sex isn't as complicated as we make it. In Sperm Wars, evolutionary biologist Robin Baker argues that every question about human sexuality can be explained by one simple thing: sperm warfare. In the interest of promoting competition between sperm to fertilize the same egg, evolution has built men to conquer and monopolize women while women are built to seek the best genetic input on offer from potential sexual partners.
Baker reveals, through a series of provocative fictional scene, the far-reaching implications of sperm competition. 10% of children are not fathered by their "fathers;" over 99% of a man's sperm exists simply to fight off all other men's sperm; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner.
From infidelity, to homosexuality, to the female orgasm, Sperm Wars turns on every light in the bedroom. Now with new material reflecting the latest research on sperm warfare, this milestone of popular science will still surprise, entertain, and even shock.

About the author

For video interviews and a wider-ranging biography, to read both praise for and criticism of his books, and to see the controversies they have triggered, visit www.robin-baker.com.
Dr Robin Baker was born in Wiltshire, England in 1944, and grew up in the small village of Manningford Bruce in the Vale of Pewsey. The tiny 2-room school he attended had fewer than 30 pupils, with all the under 7s taught in one room and all the 7-11 year olds in the other. Between the ages of 11 and 18 he attended the nearby Marlborough Grammar School where coincidentally, 30 years earlier, the author William Golding had also been educated; all later pupils were expected to be very familiar with Golding's classic book Lord of the Flies.
After obtaining a First Class Honours degree in Zoology, then a PhD, at the University of Bristol, Robin Baker lectured in Zoology at the Universities of first Newcastle-upon-Tyne and then Manchester where, in 1981, he became Reader in Zoology in the School of Biological Sciences. In 1996 he left academic life to concentrate on his career in writing and broadcasting.
He has published over one hundred scientific papers and many books. These include the international bestseller SPERM WARS which was based on his own lab's original research on human sexuality and which has so far been translated into 23 languages. His work and ideas on the evolution of human behaviour have been featured in many television programmes around the world.
His first novel PRIMAL - described by many as an adult LORD OF THE FLIES - was published in the UK and USA in 2009. In 2010-11 it will also be published in translation in Holland, Israel, France, Brazil and the Czech Republic.
Since 2002 he has lived in the foothills of the Spanish Sierras with his partner, the writer Elizabeth Oram, and their family. He has six children.

In one chapter he mentions that if we trace our linage back about 8 or 9 generations, we would find that we are related to ether a bisexual or a rapist or both. And if these events didn't take place, we would not exist today. He's saying; that "WE ALL" are related to one of these two kinds of people in one way or another.
... I know its a lot to take in. Robin Baker isn't saying that we should follow the same immoral steps like our ancestors did in order to reproduce, you have to realize that 8 or 9 generations ago it was a different world back then. Plagues and diseases were common then and it was important to reproduce cause most people then lived to the age of 30. It's strong probable fact. And it's quite a large and bold statement to say that we all share an ancestor who was a rapist, but this and much more will tell you, not so much as why, but how you got here.
I read in a couple other reviews for this book that a lot of the "science" Baker writes about has been proved wrong. One of the reviewers actually posted a link to a scientific article which conducted some experiments contradictory to Baker's research, so if you feel inclined it's on this website somewhere.
Anyway, the book did have a couple (valid) discoveries that were new to me, so all was not lost. Just wish Baker had done a better job of backing up his research!

It’s a fascinating look at the primal motivations behind a lot of human sexual behaviour. It’s helped me understand myself a bit better as well as a lot of my previous experiences. I also better understand my friends, family and the deeply rooted underlying motivations related to all forms of human sexual dynamics.
These fictional Scenes are a fun read, sometimes funny and the explanations are very educative but fundamentally they explain a lot and this could legitimately alter your perspective on of your sexual behaviour perhaps for life. Not a negative thing in my estimation.
Good book. Highly recommend.
Si vous avez l'habitude des livres sur les relations homme-femme vous aller retrouver beaucoup de notions que vous connaissez déjà, mais juste pour la section "She wants the killer in you" ce livre vaut son prix !
