Some latest news: Researchers identified something caused "competition of sperm", that they think, has developed to guarantee the genetic future. In sexual reproduction, about a natural choice in general think as something, that happens up to - and actually conducts to - the Big event. This reflection keeps, for example, that we are near from physical features which speak us, that our partner is healthy and will give us chance of struggle to continue our genetic origin. But new article suggests, that the man has developed mechanisms to pass on his genes during postconnection also, the phenomenon duplicated "competition of sperm. "
In this article researchers describe it as " an inevitable consequence of the men competing for Fertilisations. "

For monogamous versions, competition of sperm can seem beside the point. But according to authors, additional educational connections (that is affairs) it seems, an essential part of our hereditary history and, evolutionarily conversation, could write down disaster. The man which female partner is employed in the some people independent entertainments can involuntarily invest his(its) resources - the foodstuffs, protection, an estimation of the credit - in genetically untied posterity.
But competition of sperm - not only biology. According to authors, a lot of sexual behaviours such as deep pushing copulatory can function to remove the competitor sperm. Sexual partners inform, that men push more deeply and quickly in a vagina after statements about incorrectness. The same periods of division it the quantity of sperm of increase in man's sex can also help to explain, that more and more lewd men of the person of feelings develop after the long periods of time except for their assistant. That is the man can want to copulate as soon as possible as insurance upon probable connection of extra-pair.
These last results conduct us to ask a question that people have developed other unopened ways in the world dictated " a survival of the most suitable. " Actually, authors compare sexual adaptation to the phenomenon of Cold war " the Sexual conflict between men and women, " makes coevolutionary race of arms between sexes.
