Where did cavemen get leather from?

Cavemen obtained leather primarily from the animals they hunted, such as deer, bison, and other mammals. After killing these animals for food, they would use the hides to create clothing, shelter, and tools. The tanning process was rudimentary, involving methods like smoking or drying the skins to preserve them and make them more durable. This allowed early humans to utilize every part of the animal, maximizing their resources.
