Yes, many PAs still (unconsciously, anthropocentrically) believe there'sa fundamental difference: humans are "higher" than apes & other animals.
It's not: our evolution underwent special circumstances, but: we are animals like all others:
all naked & fat mammals live in warm(er) waters - we wear clothes, and probably lost weight, but so did our ancestors.
This is confirmed by everything we know: our very big brains (DHA), our "linear" build, our flat feet etc.:
only incredible imbeciles still believe their Pleistocene ancestors ran after antelopes.
