Diana:
The fact that we are all human beings, and that there are no “pure” groups within our species, does not mean that we are all alike, or that different groups do not have different propensities associated with varying gene frequencies. Evolution is ongoing and is influenced by cultural as well as environmental factors. I think that it is reasonable to suppose that a relatively homogenous hierarchically arranged agricultural civilization such as the Han Chinese would value conformity and attachment to place; whereas, those groups that live in marginal habitats and have to hunt hard for every bite of food would value personal physical bravery and the ability to explore far away places in search of sustenance. In an ancient civilized society one might hope that one’s offspring would marry up the social ladder, but in a savage society such as ours it is best to screw the biggest meanest most far ranging hunter. Such choices have evolutionary consequences. I do not know to what extent the ability to find one’s way around is genetically based, but I do know that the worldwide caving community is overwhelmingly white despite the admixture of just enough diversity so that leftist intellectuals can trot out the straw man of genetic “impurity” to prove that we are all one big happy family.

Truly your uninformed speculations on the peoples of the world have nothing to do with this forum. FWIW, a better source about the historical migration of human populations, derived from analysis of ancient DNA (much of which has been preserved in caves) can be found by consulting the work of David Reich, the author of “Who We Are and How We Got Here”: https://reich.hms.harvard.edu https://smile.amazon.com/Who-Are-How-Got-Here/dp/110187032X/ref=sr_1_2?ie=UTF8 <https://smile.amazon.com/Who-Are-How-Got-Here/dp/110187032X/ref=sr_1_2?ie=UTF8&qid=1551205927&sr=8-2&keywords=who+we+are+and+how+we+got+here> &qid=1551205927&sr=8-2&keywords=who+we+are+and+how+we+got+here https://www.youtube.com/watch?v=990052wQywM <https://www.youtube.com/watch?v=990052wQywM&t=11s> &t=11s Diana ************************************************** Diana R.
