| | Pennisi: Did Cooked Tubers Spur the Evolution of Big Brains? (Site not responding. Last check: 2007-10-17) |
 | | Already this work, which Wrangham has presented at meetings, has provoked skepticism, for it challenges the current dogma that meat-eating spurred the evolution of Homo erectus, the 1.8- million-year-old species whom some anthropologists say was the first to possess many humanlike traits. |
 | | But Wrangham and his Harvard team think a range of evidence, from archaeology to studies of primates and modern human societies, argues against that scenario. |
 | | He says Wrangham's team "downplay[s] lots of sound evidence that we have [for meat-eating and fire use] and [accepts] at face value problematic evidence." A major problem for the theory, notes Hill, is that where there's cooking smoke, there must be fire. |
