Many animals are much stronger, and/or weigh much more, than humans. despite these apparent weaknesses, early humans were able to hunt, kill, and control most animal populations. how is this possible?

Humans have a advantage over animals because humans have a working logic system, to explain this better, we can learn from things, while animals like bears, don't have much background knowledge on hunting us, just because they can't protect themselves from the multiple weapons we had.
