complex life most likely does. it’s not that arrogant really when u think about it. life needs to be able to create and preserve energy. it’s much harder to create energy when ur environment is incredibly cold. and much harder to preserve energy due to that reason as well.

if anything we've become less efficient at it. in older days we'd use the bones for stock/arrows/tools etc. we'd use the skin for leathers. sinew for string/rope. fat for fuel and preserving and soap. meat and organ meat for food. nowadays we throw most of it out to waste, organ meat barely gets eaten. leather = murder to some people so its used less and less in clothing taken over by much higher environmental impacting synthetic leather. i've spent a project on waste meats for biofuel and theres so much crap that just doesnt get used anymore.

honestly play unmodded or lightly modded and just wing it on the games not bothering too much with custom stuff.
