the acquatic theory
hmmm..what is it all about?!
if you are as curiouse as I was when i first heard of it, on the side you can find some more links about it.

btw,what i though could be intersting one of the evidence that seems to support the theory, one sentence I found on the wikipedia under "aquatic ape hipotesis":

"Kawamura in 1962 observed a troop of Japanese macaques developing bipedalism in water through cleaning sweet potatoes therein."


at the Laboratory of Physical Anthropology, Kyoto University they
found out that Japanese macaques consume more energy when using bipedalism.


comparison of acquatic hipotesis with terrestrial models...
