The Difference At McDonalds!

According to research by the German based, Max Planck Institute for Evolutionary Anthropology, male chimpanzees who share the meat they have hunted with a female chimp are able to copulate with their mate twice as much as those that do not share at all.

Apparently, meat is an important part of a chimp's diet and the female is not a successful hunter - hence she is very grateful.

When you carry the theory over to the human race, it must explain why McDonalds has been such a success .... pass the fries!!
