Chimpanzee 'Adam' lived one million years ago

Scientists have determined that chimpanzees descended from a common ancestor that predated humans.
The research, which was headed up by Professor Mark Jobling from the University of Leicesterís Department of Genetics, involved building up a detailed genealogical tree by investigating how certain DNA sequences were passed down through generations of primates.

Their findings showed that the earliest chimpanzee dates back one million years while the earliest gorilla dates back 100,000 years. The earliest human, by contrast, dates back 200,000 years.
"This suggests that over the long period of human evolution our choice of partners has not been a free-for-all, and that itís likely that humans have practiced a polygynous system where a few men have access to most of the women, and many men donít have access Ė over our evolutionary history as a species," said Professor Jobling.

"This is more like the gorilla system than the chimpanzee Ďmultimale-multifemaleí mating system."

A trip to a local bar could have confirmed this!! Sorry... just getting my Sunday afternoon entertainment fix Carry on!

The chimp system sounds a lot more fun, beta males get a chance under it at least.

While the alpha males are fighting over the females, the beta males have it off with the females.

So the rest of half monkeys half man without access to females were doing what exactly ? Is that the beginning of the gay activism ?

Other studies have shown that a woman is less likely to become pregnant from her regular sexual partner then she is from a "one night stand". This shows that, historically, women would mate with one male for security, and reproduce with another male for preferred physical traits. In small tribes this would usually result in the majority of the offspring coming from 1 or 2 "alpha" males while the females continued to be mated to "beta" males without successfully reproduce the "beta" males genes
