"...among the derived alleles that are at low frequency in Yoruba and at high frequency in east Asians, we find that essentially all of these alleles are at intermediate frequency in Europeans...We also observed that for most of these SNPs, the allele frequencies in the Americas are similar to Han frequencies, suggesting that in most cases these alleles were already at high frequency prior to colonization of the Americas some 15,000 years ago ... Together, the latter observations suggest that perhaps the east Asian sweeps tend to be relatively old..."
The American midwestern city of Cahokia around 1100 was larger than some European cities. The Euro city most often compared is London.
Cahokia is (was) across the river from St Louis and is on the way for many west ward vacations. A visit is advised on trips to Yellowstone et al.
