one scenario is that we were living on the savannah and we used our excellent eyesight to see where vultures were circling over corpses...we then used our running ability to get there faster than the animals could eat all the corpses...we then used our hands to lift up rocks and throw them at predators eating the corpse and scare them off...we then lifted the rocks and cracked the bones and then ate the calorie rich marrow...
so we needed a tall standing bipedal stance and good eyesight to see into the distance, and good long distance running ability, and bare skin and not much hair so that the air could cool us while we ran fast to the corpse...we needed hands and opposable thumbs and innate math ability to throw rocks accurately and then crack the bones...

I'm not talking about any aspect of our physiology but our ability to take in and maintain high oxygen levels under conditions where we are rapidly expending oxygen.
Also, you can only get there faster than the other animals if they're not already seeing (or smelling) the same thing the vultures are looking at.

Not everything has an evolutionary purpose. Sometimes, some things are side effects.
I've always thought persistent hunting (>20 miles) didn't really make sense.
I think it's more likely that our bodies evolved to be capable of long-distance exercise for hunting, running away from attackers, etc., but that following animals to exhaustion didn't really seem realistic.
