Big muscles, heart, long legs, big hands etc do not bring with it obstetric difficulties like large brain does
Erectus had an estimated neuron count of 62 bn neurons. http://m.pnas.org/content/109/45/18571.full … If we could have a brain his size and eat less to power it
Then, of course, our brains would have stayed that size. 86 bn neurons needs about 520 kcal to sustain the brain
It'd be considerably less if we had erectus brains, and as seen, it's perfectly possible to have normal IQs with erectus brains
Hoped for more of a back and fourth tbh.
Quick back and forth are not a very productive way to do science. This is not a media show.
