alt Hacker News> If you did attempt to classify people into races based on something scientific like genetics, you would end up with hundreds of thousands of “races”. With even more fine tooth classification, you could subdivide those people into further sub groups that becomes indistinguishable from just classifying extended families.
'Biologically speaking', wouldn't that 'just' be something like breeds?
Yeah, but at the end of the day, all of this classification is very arbitrary. Until you can come up with a measurable system like “8% genetic differences are defined as a different species” or “can successfully interbreed with viable non-sterile offspring” or something it’s all just a useful pneumonic to understand the world, but it’s not really objective science. Dog breeds are notoriously subjective and just depends on what the registry in the place wanted to do.
