>While only 40 percent of the population about 6,000 years ago comes from the Steppes, 100 percent of the Y chromosomes do.
From reading this article it seems another way that this could be phrased, is that we are all the descendants of perpetrators of genocide.
- Noumenon72 8y agoDon't forget the rape! 100% of your Ys coming from one place is the opposite of "mutt", too. But the only way you can get to do race science is by coming to the conclusion "There's no such thing as race" first, and making the details sound boring enough that nobody asks.
- mirimir 8y agoYeah, the title ought to be something like "DNA reveals many of us are descendants of genocide and rape". Edit: So I clearly have some Mongol heritage. And so does my wife, who's Ukrainian. One of her grandmothers could have easily passed as a native in Mongolia.
- dqpb 8y agoThe concept of race has always sounded like total bullshit to me. Do you have a definition that makes any sense?
- toasterlovin 8y agoEasy: the definition is what most people mean when they use the term. Paraphrased: phenotypic characteristics that correlate with ancestry.
- haihaibye 8y agoSequence the world and run them through a clustering algorithm, picking how many clusters you get: 2 clusters: African and non-African 5 clusters: African, European, Asian, PNG/Australian Aboriginal, Native Americans All the way to: 1 billion clusters: Individual families When most people think of race they are talking about the number of groups that make clusters of major continents, where there wasn't much gene flow until 1492. Google PCA ancestry (PC term for race) eg gnomAD: https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcSZ-lBFuHuVO2g446dI21P0F8oqcmLYAGZAXy-Yg9uJ5ULt2Pxd https://encrypted-tbn0.gstatic.com/images?q=tbn%3AANd9GcSZ-l... Self reported race matches genetically determined race at rates in the high 90s. A way to think about it without clustering etc: People separated (usually by geography) long enough that they bred mostly amongst themselves, and developed characteristics different than other groups. Yes, you can walk from Amsterdam to Beijing and see a gradient of people the whole way - but that doesn't mean you can't tell the difference between a Chinese person and a Dutchman.
- growlist 8y agoHow about 'ethnic group' then instead? The evidence of difference is right before our eyes. Just watch athletics!
- astazangasta 8y agoApparently you're unfamiliar with the sorry state of the gene content of the Y chromosome.
