I have read that although certainly other land animals are much faster over short distances, a human can run down any other animal over time, so that if a human is hunting like a gazelle, etc. eventually the human will catch up. I am wondering if this is purely a physical thing or if humans, knowing how to pace themselves, avoid exhaustion while the gazelle just runs as fast as it can and then collapses -- is it possibly because humans are smarter that they are better long-distance runners? (Now, some birds are able to fly for thousands of miles and I guess also in water we can't compete.)
EDIT: I understand that humans have some physical attributes that contribute to their long-distance abilities but is the ability to understand pacing also part of it?
