I meant half a million years ago when (so the narrative goes) Big Leader Ug ruled a small band of early humans by physical force and could club anyone who wanted to mate with Ug's Womans. I was wondering if a protracted period of this could produce an equivalent genetic effect to a single population choke point under the relatively modern assumption that humans pair off.

Of course that doesn't mesh with the simultaneous narrative that humans haven't significantly changed biologically since then. You get that.
