How did early man survive

Are you speaking of ‘Homo sapiens’? I suggest you look up homo erectus, homo habilis, and australpolithecus afarensis. The techniques that those bands used millions of years ago are the same techniques homo sapiens used. They hunted, made clothing, and also discovered farming. They were running out of food, so they tried planting old seeds that fell to the ground. The process started over and over again, thus inventing a new way of getting healthy food. Homo sapiens gathered and gathered and now we do the same. Before, Homo habilis and erectus were carnivores, eating and hunting animals. But homo sapiens are eating healthier to get energy. Since they didn’t want anything to go to waste, they took the leftover bone and carved it with sharp flint so they can shoot it into the animal’s heart. Homo sapiens took the skin and cleaned it, made clothes, and now they’ve used all the parts of the animal.
