David Reich ist ein US-amerikanischer Human- und Populationsgenetiker.

Er ist der Sohn des Psychiatrie-Professors Walter Reich . David Reich studierte zunächst Soziologie an der Harvard University, wandte sich dann aber der Physik zu und wurde an der Universität Oxford in Zoologie promoviert. Ab 2003 war er an der Harvard Medical School, wo er Professor für Genetik ist.

2006 untersuchte er die genetische Abspaltung des Menschen von den Menschenaffen . Danach gab es über mehrere Millionen Jahre noch eine Vermischung bevor vor 6,3 bis 4,5 Millionen Jahre die endgültige Trennung einsetzte. Ab 2010 untersuchte er die genetische Trennung bzw. Vermischung von modernen Menschen und Neandertalern.2009 untersuchte er die genetische Entwicklung der Bevölkerung in Indien. Es konnten zwei große genetische Gruppen unterschieden werden: Ancestral North Indians und Ancestral South Indians . Die ANI haben Verbindung zu Populationen in Zentralasien, dem Nahen Osten und Europa, die ASI zu keiner Gruppe außerhalb Indiens. Ihre Spaltung fand vor etwa 50.000 Jahren statt. Zwischen 2200 v. Chr. und 100 n. Chr. kam es zu einer Durchmischung beider Gruppen , danach kaum noch.

2011 stellte er mit Simon Myers eine genetische Karte von Afro-Amerikanern auf. Dabei fanden sie rund 2 Millionen Rekombinationsereignisse im genetischen Material von 30.000 Afro-Amerikanern und werteten diese aus. Sie fanden deutliche Unterschiede zur Rekombination bei US-Amerikaner mit europäischen Wurzeln bzw. Europäern.

2018 löste er durch einen Beitrag zur New York Times einen Streit aus, da er, wenn auch in Anführungszeichen, den Begriff Rasse gebrauchte und genetische Unterschiede auch komplexerer Art zwischen Rassen feststellte. Dafür wurde er von Sozialwissenschaftlern wie Alan Goodman und Ann Morning kritisiert.2017 erhielt er den Dan-David-Preis, für 2019 wurden ihm der NAS Award in Molecular Biology, der Wiley Prize in Biomedical Sciences und die Darwin-Wallace-Medaille zugesprochen.

“Ideologies that seek a return to a mythical purity are flying in the face of hard science.”

“Ancient DNA available from this time in Anatolia shows no evidence of steppe ancestry similar to that in the Yamnaya (although the evidence here is circumstantial as no ancient DNA from the Hittites themselves has yet been published). This suggests to me that the most likely location of the population that first spoke an Indo-European language was south of the Caucasus Mountains, perhaps in present-day Iran or Armenia, because ancient DNA from people who lived there matches what we would expect for a source population both for the Yamnaya and for ancient Anatolians. If this scenario is right the population sent one branch up into the steppe-mixing with steppe hunter-gatherers in a one-to-one ratio to become the Yamnaya as described earlier- and another to Anatolia to found the ancestors of people there who spoke languages such as Hittite.”

“People often think that Europeans are homogeneous group that arrived in a simple way there maybe 40 or 50 thousand years ago maybe based on the archaeology and just kind of sat there until they became the Europeans they are today, but that's probably not true: the Europeans today are a replacement population who came in much more recently and replaced the people who were there originally 40 thousand years ago.”

““Whites” are not derived from a population that existed from time immemorial, as some people believe. Instead, “whites” represent a mixture of four ancient populations that lived 10,000 years ago and were each as different from one another as Europeans and East Asians are today.”

How Genetics Is Changing Our Understanding of ‘Race’ https://www.nytimes.com/2018/03/23/opinion/sunday/genetics-race.html, NY Times, 23 March, 2018

“About ten thousand years ago there were at least four major populations in West Eurasia — the farmers of the Fertile Crescent, the farmers of Iran, the hunter-gatherers of central and western Europe, and the hunter-gatherers of eastern Europe. All these populations differed from one another as much as Europeans differ from East Asians today. Scholars interested in trying to create ancestry-based racial classifications, had they lived ten thousand years ago, would have categorized these groups as "races," even though none of these groups survives in unmixed form today.”
