In a docu I heard we are pretty good at endurance hunting. We seem to have good endurance and move in a way that conserves energy, we basically can chase animals to death. That still needs some basic tools … a spear and something to carry water. The biggest advantage isn’t just that we can use tools, but that we can use them while running. That we are smart enough to do tracking also allows us to not bother if we can’t keep up with an animal’s peak speed, since most can’t keep it up for long either. So one person should be okay to hunt down a single animal.
