The mystery of why humans are the only animals to have chins (下巴) may have been solved by scientists who suggest that it is connected to the invention of cooking.
A paper from the University of Florida tries to explain exactly why humans 一 unlike all other primates (灵长目动物) 一have chins.
A team led by Dr James Pampush collected information from more than 100 kinds of primate and compared it with historical information. Computer modelling found how the chin developed.
Random genetic change(随机的基因变化)was ruled out because the chin developed 77 times faster than the average genetic change. And the study finds no evidence that it -served a useful purpose. The research,published in the Journal of Human Evolution,suggests the chin is a by-product of another event. In this case,the event could well be the invention of cooking.
“The chin began to appear as a result of major changes six million years earlier. The arrival of cooking and softer food meant humans no longer needed big teeth and powerful jaws .and over the next two million years to 200,000 years both got smaller and the chin was bora ,” said Dr Pampush. “My guess is that it most likely happened around two million years ago when there was a jump in brain size. The changes which finally lead to the chin are directly related to cooking,and indirectly related to larger brains and bodies."
Dr Pampush's new theory goes against previous suggestions that the chin was an example of sexual selection,with attractive chins marking out men who are likely to make good mates(配偶) . The fact that both men and women have chins means the theory is unlikely.
Another theory put forward in the past said that the chin was a way to balance out the stress of chewing,but Dr Pampush also threw doubt on that idea.
