What are everyone's thoughts on this? I think it provides some interesting counter-arguments to a lot of the more extreme alt-right positions regarding the differences between the races. It seems like (unlike gender!) race does appear to be on a spectrum rather than being distinct groups.
And should we extract from this that certain genetic make-ups don't have a much decreased capacity or willingness to accept Western values? Cause it wouldn't be the first time.
That video was a whole lot of science to get to the simple point that race appears to be a social construct. It demonstrates what you would expect after so many years of isolation. With the modern lack of isolation we will move in the opposite direction.(i.e. our hostess) And that is awesome. Unfortunately, we still try to hold onto our attachment to tribalism based on certain physical traits.
Similar examples also exist in Europe, here's a photo of Sami people who are indigenous of Northern Scandinavia. https://upload.wikimedia.org/wikipedia/commons/thumb/6/6b/Three_S%C3%A1mi_Lapp_women%2C_c1890s.jpg/220px-Three_S%C3%A1mi_Lapp_women%2C_c1890s.jpg
Here's a picture of Ainu people who are the indigenous population of Hokkaido Island in Japan. Notice the second guy on the right. He looks more European than Asian to me. https://upload.wikimedia.org/wikipedia/commons/d/d7/AinuGroup.JPG
That said, yes race is obviously a spectrum. A while ago, I was watching video compilations of faces from different Turkic tribes inbetween Europe, Asia and the Middle East and I've seen traits from all three areas. This Uyghur girl is a good example https://upload.wikimedia.org/wikipedia/commons/0/05/Uyghur_girl_in_Turpan%2C_Xinjiang%2C_China_-_20050712.jpg
My own people have significant native american admixture although this varies greatly from an individual to another. I myself tan abnormally fast compare to other white people. I have a cousin who was able to get an indian card and got her college paid by the government. This is ridiculous I admit but we do have native ancestry within 5 generations and some associations have very loose critera. I've been thinking a lot about taking a genetic test because I would really want to know how much of my dna comes from natives.
Most genetic graphics circulating on the Internet are 2-dimensional projections using principal component (PC) analysis. I'm in the field of mathematics but most people have no idea what PC is. Good thing he pointed out the data is not 2-dimensional but linear combinations of many variables.
That was a good genetics crash course. He really goes into the details and explains lesser known genetic concepts like FST which I had never heard of.
