The human mind may draw arbitrary and subjective ellipses over a collection of individuals. Below, I show an unsupervised model-based clustering of 1007 West Eurasians. k=14 was chosen (k=1:20 allowed), showing how arbitrary "European"/"Aryan" clusters (as in the quoted post) are

"The Ecumenical Patriarchate expressed deep sorrow and surprise upon learning that the competent Egyptian court called into question the longstanding ownership status of the historic Holy Monastery of Sinai." …-ecumenical-patriarchate.visitlink.me/-dxWGm

Here are the cluster assignments for k=2 to k=16. I use the lower right panel to show the BIC (maximized at k=14 as in the quoted post at the 12-16 plateau). Notice how "European" vs. "non-European", so beloved by some, has an atrociously low BIC: a gross oversimplification.
