Earlier quoted context omitted.
There is no biological basis for the word race.
I find this meme annoying because it so often misses the point (as I'd argue it does in this particular discussion). Yes, races are largely a social concept. However, once society has defined races based on whatever phenotypes that are in fashion at the time, it turns out that yes, there is a biological and genetic basis for those phenotypes . It's conceivable that this biological basis could be targeted by some gene…
- where we see a person - who this person is with - what clothes the person wears - what a person smells like - body language - spoken language - the manner in which they speak (loud, soft, etc.) - the way they walk - all sorts of other cultural markers (like stance, eye contact, etc.)
I suspect that all these contextual, largely non-biological factors play a huge role in how we decide a person's race. Possibly so much so that the biological markers we do have available are mostly useless.
Please correct me if I'm wrong though; I am far from an expert in this area!
