Our analysis indicates that the San population of southern Africa diverged from other human populations approximately 108–157 thousand years ago, that Eurasians diverged from an ancestral African population 38–64 thousand years ago, and that the effective population size of the ancestors of all modern humans was ~9,000.
The cool bits about this study:
genome-wide analysis, unlike previous studies which only focused on mDNA or the Y chromosome
date for San divergence gets pushed way earlier
simultaneous analysis of multiple populations
confirmation of Out-of-Africa migrations at about 50kya
“It’s clearly a crisis of two things: of consciousness and conditioning. We have the technological power, the engineering skills to save our planet, to cure disease, to feed the hungry, to end war; But we lack the intellectual vision, the ability to change our minds. We must decondition ourselves from 10,000 years of bad behavior. And, it’s not easy.”—Terence McKenna (via elige)
“It is our task to discover among all the varieties of human behavior those that are common to all humanity. By a study of the universality of cultures anthropology may help us to shape the future course of mankind.”—
- Franz Boas, the father of American anthropology.
[This is the exact reason I am studying Anthropology, and I’ve seen it expressed in several of my ANTH200 readings already.]
