I think they benefited from slower runs across the course of days rather than sprints to chase game. Lots of animals are faster than humans, but in order to cool down they have to stop. From what I've read, humans' ability to run and stay cool through sweating allowed them to, over the course of days track and just simply wear out animals to the point the animal would just collapse from exhaustion.
