She really butchered aquatic ape theory, but the theory suggests that we may have a semi aquatic ancestor due to the fact that we have adaptations often found in aquatic mammals such as being relatively hairless, longer legs which are good for wading into water, we can survive at higher depth than other primates, and we have more webbing on our fingers and toes than our primate relatives do and a brain to body ratio often found in aquatic mammals,and very efficient muscles when it comes to oxygen use, most of these adaptations are what made humans successful endurance hunters in africa. And of course fatasses threw in blubber to try and excuse their shitty lifestyle choices, because not even science is safe from the ham delusion.
