Learning to throw sharp weapons at animals did NOT enable people to run faster: In the time before projectile weapons like spears, humans needed to get very close to their prey in order to kill them. Usually, prey like antelope and deer can move much more quickly than humans over short distances. However, if the human hunters could force the prey to run longer distances, the animals would become exhausted. That gave prehistoric hunters an advantage. Humans who could endure the long-⁠distance chase necessary for a successful hunt were the humans who ate and had food to share. They were the humans who started families and became ancestors to all of us. (Из контекста абзаца следует, что опции 2–4 не верны.)
