I'm thinking of something and I have a multitude of options, but the PoD is so far back that the consequences can literally be ludicrous (as well as relying upon unconfirmed theories which can probably never be confirmed or disproven). Now we know that the neanderthals dissappeared due to a multitude of factors (low population density, campi flegrei ashing over coincidentally their entire territory, intermixing and predation by modern humans as well as their own people (ah, the good ol' times when eating fellow sapients was a completely normal thing to do), neophobia and disease introduction) but it is perfectly plausible to have a group migrate to an isolated area (they did OTL) but adapt to the new situation and increase their densities, resulting in a neanderthal (at least 50% but preferably higher) population surviving to modern day. Would that be considered an evolution PoD and therefore ASB or not (and if not, what are the best locations to put them in)
And, are highly contested theories considered ASB too, even though they could have happened (talking about the solutrean hypothesis)
