And where did those earlier people go?"</i><br /><br /><i>"An invading group can come to genetically dominate the future population of an area, but it never happens that the genes of the original inhabitants completely disappear."</i><br /><br />What if the people who were already present were not very numerous, or were not settled very densely?<br /><br />Or what if there was an event similar to the Columbian Exchange, and the locals fell prey to some contagious disease which they lacked immunity for? If they were wiped out completely, that could explain a complete disappearance of genetic materials.<br /><br />Or what if the two groups simply didn't interbreed at all for some reason, and the larger incoming group managed to outcompete the original inhabitants?<br /><br />Or what if there actually weren't any significant genetic differences between the two groups, both being derived from the same origins, with the "local" population having simply been a smaller, earlier wave of immigration? Suppose the Clovis were literally the same people, just migrating later, in larger numbers, and with greater technological and cultural progression resulting in their artifacts being distinct.<br /><br />That last possibility might also explain how the Clovis culture spread so quickly, as the two groups would be able to quickly reintegrate. It'd be like an army sending scouts ahead to get the lay of the land, and then relying on the information those scouts gathered when the bulk of the unit arrived.G. Verlorennoreply@blogger.com
