Ein mathematisches Modell zeigt:
Wiederholte Vermischung mit Homo sapiens ließ die Neandertaler in nur 10.000 Jahren genetisch verschwinden.

Abstract
„The disappearance of Neanderthals remains a subject of intense debate, with competing hypotheses attributing their demise to demographic decline, environmental change, competition with Homo sapiens, or genetic assimilation. Here, we present a mathematical model demonstrating that small-scale Homo sapiens immigrations into Neanderthal populations, providing recurrent gene mixing, could have led to almost complete genetic substitution over 10,000–30,000 years. Our model, grounded in neutral species drift, does not require selective advantage or catastrophic events but shows that sustained gene flow from a demographically larger species could account for Neanderthals’ genetic absorption into modern humans within a time-frame consistent with archaeological evidence. This scenario aligns with growing evidence of interbreeding and genetic introgression through recurrent H. sapiens immigration waves, providing a parsimonious explanation for the observed patterns of Neanderthal ancestry in present-day Eurasian populations. Although other factors may have contributed to the decline of Neanderthals, our results highlight genetic admixture as a possible key mechanism driving their disappearance.“ (…)

Kommentar GB:
Diese hier entfaltete Hypothese hat m.E. sehr viel für sich.
