> ... vocal cord development ...

I've read, from a few separate sources that were not research papers, something similar that claimed the development was a result of existing in semi-aquatic environments such as home on land but swimming for food/safety. I neither agree or disagree (not my field, I don't possess appropriate background/information), but I do think of it when evolution of vocal cords is mentioned.

I don't recall the sources ATM, possibly something out of CoEvolution Quarterly or Bucky Fuller. Again, not research papers.

Semi-aquatic environments make sense if you look at our brains dependency on DHA (seafood is a rich source) and the hypothesis that our fingers get wrinkly in water after a while to improve grip.

Aren't we a lot more evolved for hunting animals on foot? The whole thing with us losing our fur and sweating with the whole body, adaptations to running and throwing stuff, all of this makes us better hunters, but not necessarilly fushermen.
