  • How did cavemen survive?

    Q: How did cavemen survive?

    A: 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.
