How promiscuous women made men the shape they are

SCIENTISTS claim to have discovered the reason that men’s testicles are the size that they are: it’s all to do with the infidelity of our female ancestors.

A study of the evolution of sperm has revealed that the average human female does anything but stand by her man: like many other primates, she is not at all averse to promiscuity if she can get away with it.

Research by a team at the University of Chicago, led by Bruce Lahn, suggests that men are more prone to stray than women, but the notion that human females long for nothing but a stable, monogamous relationship with Mr Right is wrong.

The study, published today in the journal Nature Genetics, examined the evolution of male sperm among 12 species of primate, including human beings. Sperm is useful for the investigation of a species’ sexual practices in the distant past, as its characteristics are largely determined by mating patterns.

This would be a lot funnier if I was joking. :(

Act all moody and then tell her/him that you came up positive on your recent HIV test.

It'll be a Laff Riot!
