also the idea that we still have no idea whether homo sapiens became the only homo-species left on the planet because we either inbred with them OR committed very efficient genocide. were early humans lovers or murderers?? no one knows, because we're super likely to do either. homo sapiens, amirite?
@izzy I've also encountered a theory that suggests that Sapiens was the first hominid to do much exploring beyond what was immediately visible (like going to the other side of the lake that disappears into the horizon). The ones that survived reaped great benefits.
