These show that by 600,000 years ago Peking Man12 (as the excavators dubbed the Zhoukoudian ape-men) had diverged from tall, lanky Africans like the Turkana Boy toward a stockier form, better suited to cold. Peking Men were typically around five feet three inches tall and less hairy than modern apes, though if you ran into one on Main Street it would certainly be disconcerting. They had short, wide faces, with low, flat foreheads, a heavy single eyebrow, and a big jaw with almost no chin.
