But that's only if you take a very narrow definition of what "human" is. I think a better definition wouldn't be as limited on the specific isolated organism, but rather on the organism within its environment – and that includes society as well as the actual physical environment. Nature/biology isn't very exclusionary and a lot of things are better looked at as ecosystems.
From that perspective, the "human" has definitely changed since a few thousand years ago.
It really hasn't though. Customs and laws may change but the behaviors of people in their environments remain pretty much the same. It's very eye opening.
