You think early human could firstly evolve big brains for trajectory calculations or some form of heat control? What do you think requires more energy and would have come sooner?
Monkeys can throw they just lack the shoulder to be good at it.
I think learning how to throw accurately is much easier from an evolutionary perspective than heat dissipation that uses a lot of resources combined with the least calorie efficient hunting method.
First throwing, then running long distances to have a larger hunting range. Seems a far more natural sequence to me.
