People who say there's no such thing as race are complete charlatans playing semantic word games.
That is comically retarded. Like do you have any understanding of the words you are using ?
If there's no genetic justification, how would it be possible to trivially determine someone's race just from their DNA ?
Genetic ancestry is determined by correlation with geographic origins and population. In other words, where a set of genetic markers are highly concentrated. It says nothing about race.
This was my thinking, also. Good cluster of links.
Nobody in race sciences (anthropology, etc) claim that there are only unique races that are separate from each other and don't mix. This is a clear strawman.
The fact that there is mixing between races does not mean that races don't exist. You can make an emulsion out of water and oil, but water and oil still are their own things.
And the science has all kinds of specific categorization for human groups that go way beyond the rough separation into 3-4 main races. All the mixing, separation, migration, isolation, etc have been taken into account.
It's a pity this kind of topic/science is basically a taboo in the Western World and for real info and honest discussion have to go to other systems/countries/languages.
Between us, you are clearly the one with no clue about what he's talking about.
There’s more genetic variation within any so-called racial group than between groups, race mixing or not. Clearly, 'race' has no genetic justification.
You must be one of those clueless people who think that sex is fluid and is a social construct because there is in certain characteristics a bigger difference within each sex than between the medium of each sexes.
Shortly:
- Unique how? Optimally genetically, but this has practical problems that the field of paleogenetics is trying to work on. Until then must use: classical morphological features, odontology, dermatoglyphics, biochemical characteristics.
- How long enough? Depends on the type of group. There are different levels of human group classification, both above the traditionally understood "races" and a lot below that.
