8,000 yrs old may have started with Finnish Lapps (have high concentration of RH Negative Blood Type B TODAY )
Rates of lactose intolerance.
African Americans Adults/79%
Mexicans from rural communities/73.8%
North American Jews/68.8%
Mexican American Males/55%
African American Children/45%
Caucasians of N. European and Scandinavian decent/5%
The case is clearest and best documented for northern Europe, where there are very high percentages around the Baltic and North Seas. High levels of lactase persistence seem closely linked to Germanic and Finnic groups. Scandinavia, northern Germany, and Britain have high levels, as do the Finns and Estonians, the Finnic Izhorians west of St. Petersburg, the Mari of the middle Volga basin, and, to a lesser extent, their more distant relations, the Hungarians.
The study suggests that the lactase gene spread rapidly in the human population only after dairy livestock were introduced to Europe about 8,000 years ago.
Note: Native Americans are more inherent than any other ???
