They are the Son-in law of Neanderthals,which carries most of Neanderthal genes,Asians facial structure is different from any human in the world is due to heavy Neanderthal genes,The“caveman” legend of European is most likely link to extinct Y-haplogroup K2a branch with heavy Neanderthal genes,K2a is much much older than Q and R.

The haplogroup I and R move to Europe much later,They are not likely see a real Neanderthal,What they met the Caveman and told in their legends are likely K2a with Neanderthal genes.

This still doesn't properly explain why east asians or hapas get less neanderthal variants on 23andme than most(if not all of them) of the West Eurasian customers.

Asians facial structure is different from any human in the world is due to heavy Neanderthal genes

Nope, it's because of an other human sub-species.

Haplogroup K2a isn't the haplogroup Europeans encounter when they settled Europe.
First of all, there's not even proof European haplogroups weren't here first.

Even if that wasn't the case, here there was haplogroup C. Even if Oase1 was K2a, haplogroup K had an Asian range.

And by the way we have realized that you have picked the exact haplogroup of yours, even if there are other subclades that differ from your ethnicity that had an Asian homeland.
