> We know that Neanderthals may have had bigger brains, and may have been pushed to extinction by homo sapiens. A bigger brain will require more food and take longer to develop, potentially putting Neanderthals at an evolutionary disadvantage to humans. Where are you getting this data? Per Wikipedia (https://en.wikipedia.org/wiki/Neanderthal https://en.wikipedia.org/wiki/Neanderthal), Neanderthal brains were similar to those of modern humans: > The braincases of Neanderthal men and women averaged about 1,600 cm3 (98 cu in) and 1,300 cm3 (79 cu in) respectively, which is within the range of the values for modern humans.
