What did humans eat before agriculture was invented? ↧

By about two and a half million years ago, early humans started to occasionally eat meat. By about 2 million years ago, this happened more regularly. By probably about a million and a half years ago, humans started to get the better parts of animals. They shifted from just scavenging the leftovers to maybe getting earlier access to carcasses.
