A team of Chinese scientists has revisited an iconic anthropological dig, and their findings could shed light on any number of riddles involving our ancestors. Or, in the particular case of Peking Man, our ancient cousins. Genetic study still seems to indicate that whatever species this hominid might end up being, it isn't in our direct line of descent. That said, they're still plenty close enough to provide information about how they, and by extension we, survived in such an incredibly harsh time.
