My understanding is that humans have very limited genetic diversity compared to most other animals, because of the population bottlenecks we've been through. And further, that diversity is mostly between individuals, not between groups. The distinction is easy to see in cats vs dogs: they both have similar overall genetic diversity but two Chihuahuas have virtually all the same genes (the small angry ones) while two…
> The average european person and the average east asian person are a little bit different genetically, but way less different than any two real europeans or two east-asians are to one another. This is always touted as an “racism-is-not-only-immoral-it-is-scientifically-wrong” argument, but it is a fallacy. Example: The average height (a trait with very high heritability) of Dutch men is 6’0 feet (183 cm) and the ave…
I would not give too much credence to the various figures often given for the average height of men and women in x country without careful research, since they have highly variable degrees of support.
For years I had heard repeatedly that the average height of a man in Indonesia was 158 cm or 5ft and 2 inches. This seemed so absurd to me and provoked enough scepticism that I eventually attempted to track down the source of that figure. It turned out to be from Wikipedia and the citation was a study that measured the heights of the elderly yet all of those repeating that figure neglected to mention, or were in all likelihood entirely ignorant of, that detail. I am similarly sceptical of some of the claims made about the average height of the Dutch, the subject of which seems to be a particular favourite among height myth-mongers.
With respect to young adult men I have found that figures based on measurements obtained as part of fitness screenings for mandatory military service are the most reliable due to their large sample size (at least an order of magnitude larger than the largest academic studies) and overwhelming lack of selection and sampling bias. A minority of nations have such systems and fewer still publish the data obtained in public. Yet even this would not answer the question for the whole population.
