Richard Dawkins called Julian Jaynes’s 1976 book, The Origin of Consciousness in the Breakdown of the Bicameral Mind “either complete rubbish or a work of consummate genius, nothing in between”
Aquatic ape hypothesis is similar. It's a initially a great theory and explains many things. Only when you start to investigate other explanations, the theory starts to fall a apart. Endurance running hypothesis on the other hand seems to hold. Incidentally it explains many of the same things as aquatic ape hypothesis, and there is more supporting evidence.
