*Yes but I don't see why Bipedal walking would be better at endurance than
quadratic walking, if anything the reverse would seem more likely to me. *

Yes if you have a big brain and hands you could do that, but you can't do
that with just hands and hands evolved before big brains. What are the huge
disadvantages of evolution is that it has no foresight, even if a mutation
would give a great advantage two or three steps down the line it's not
going to get passed to the next generation unless it conveys an advantage
right now RIGHT NOW. It just doesn't understand that one step back and two
steps forward is an advance because evolution is dumb but until it got
around to impending a brain that was the only way that complex objects
could get built.

*True, but what immediate advantage would that mutation confer? *
