When Humans Started Shaving Different Parts of Our Bodies
Why Your Palms Get Sweaty When You're Excited, Scared or Nervous
In this video:
The human hand is remarkably different from that of other primates, with shorter fingers, a smaller palm and a significantly stronger thumb; of course, the most notable feature of our hands is the ability of the thumb to perfectly and comfortably oppose (come into square contact at the tips) each finger of the same hand. While we can’t know with 100% certainty all the factors that led to the evolution of our hands, it would seem it all revolves around this perfect opposability, and the various advantages that provides in certain scenarios, that has dictated the length of each finger.
