  1.  @rodolfolasparri  you do understand that brain size has more to do with size of the physical skull than anything? Yes, most basketball players have bigger brains than scientists. And phrenology, a pseudo-science that claimed that shape or size of the head makes ANY difference. Also, it's alarming how actual medical doctors still think black people have higher pain tolerance, it's extremely racist, and, OF COURSE, false! @St T. your biology teacher used extremely outdated sources. Genetics PROVEN that distinct races do not exist. There is literally no border and too many in-betweens between people of various ethnicities to group any of them as a "race." Now then the "races" you have in USA: Native, Latino, Caucasian, African or Asian-American are socio-ethnic groups within USA. They are product of social factors. In Europe, the word Caucasian means someone from Caucasus mountains (think Armenians like SOAD, Cher or Kardashians) and not "white people". Where do you put people from Caucasus? Cause they ARE Caucasian but not really white.

  2. Using CITY dwellers as genetic samples will completely muddle the result as ALL of us are mixed. The only way to have ANY semblance in results is to measure more or less isolated and homogeneous villages somewhere in the mountains or somesuch.

  3.  @BoraCM  Identical twins have identical DNA.

  4. 6:10 Thanks for telling that EVEN as seemingly clear a difference as "white" and "black" are just social constructs. That's why all this "Ancient Egyptians were white/black/brown" things are completely bogus, as the races, by definition, ARE social constructs! Mexicans, Muslims or Slavs didn't exist in Antiquity! Great example, Latinos. Nowadays, the word is used to refer mostly to American people from Mexico, central and South America. But originally, Latin meant, well, Italians. Or Arab, which is a multi-ethical identity for many nations now. Well, guess what, Jewish people in Israel have more DNA in common with Arabs in Arabian peninsula than Egyptians, who are living in Egyptian Arab Republic, where the HQ of Arab league is located.))) North African countries are Arabian by identity, a social construct. They are mostly genetically distinct from Middle East. And genetics are extremely complex, and any racial division is based more on social factors (i.e. African Americans are a distinct community formed as result of centuries of migration and segregation) then on genes, in fact you can find more genetic diversity between two separate tribes in Africa than between completely different-looking people in New York.

  5.  @rhys3350  plenty of vikings were Christian later too. @Carl no, viking is a job, a social class if you will. Not all Norsemen were vikings.
