Cavemen survived by hunting and gathering. For this reason, they did not live exclusively in caves as their name suggests. Cavemen typically lived in shelters constructed of animal hides stretched across bones, wooden lean-tos or mounds made of dirt. Neanderthals, another species of cavemen, did live in caves almost exclusively, although the harsh climates of their environment forced them to use circulating mobility and radiating mobility to survive.
Neanderthals used circulating mobility to create a number of temporary camps that were spread throughout their hunting grounds in a particular region, some of which were caves. This gave them the ability to move from place to place while they searched for the best hunting grounds. They used radiating mobility to hunt for food around one central camp. Hunting parties left the central camp and moved farther away to find food. The hunting parties always returned to their camp site after food was located. The majority of their central camp sites were caves because they suited the needs of the Neanderthals well. In addition to hunting, caveman gathered fruits, vegetables, nuts, seeds and legumes. Because farming had not been invented, they did not eat corn or grains, and dairy was not included in their diet because there were no livestock.
