Was it something that Homo Sapiens, Neanderthals, and Denisovans had in common or did they develop differently and independently? I apologize if it isn't the right sub but you're my only hope History-One-Kenobi
Hi there!
I'm afraid this isn't exactly the right sub. We do have some people who do pre-history (stuff that happened before there was writing) but I think you might be better off at /r/AskAnthropology
Thank you!
