One scientist had a theory that the reason people don’t have much hair is we fished animals out of the water. IOW, people were semi-aquatic.
Some of the earliest human settlements had large mounds of clam shells and fish bones, which kind of boosts this theory. It’s easier to grab a clam that hunt a mammoth with a spear.
People in Africa and the South still catch fish by hand.
Who was the first guy to catch a lobster and say I wonder what this tastes like?
