The fact that the rest of humanity didn't bother with persistence hunting may also be a clue that we weren't designed for that either.

Or it's a clue that we figured out that building a trap or using a weapon to kill an animal from greater distance burns a lot less calories.

For sure. And that's the point. Persistence hunting is a strategy developed by a set of humans living in one small area of the world that isn't particularly hospitable to humans. In fact, give how inhospitable the African Savannah is, it is a point against the idea that this is somehow a 'natural' state of being for us. And it makes sense, this kind of long distance running is incredibly energy intensive and injury prone - it's not a great way to make a living.

It is not as clear cut as you say, there appears to be some scientific discussion on this: https://en.wikipedia.org/wiki/Endurance_running_hypothesis
