Adjunct to that is a very active (among animals) storage metabolism that makes good use of lean times, of which every living thing has has mitigation. Lean times are at worst episodic and must be presumed to be seasonal. But a chronic deficit over a million years means only one thing: adapt or die out. Ancient humans adapted to the environments they live in, and the proof is that we are still here.
