Caucasian means a person with a Caucasoid skull structure. Skin color doesn't matter.
Not it means someone from the Caucasuan mountains like Armenians and Georgians
It did but not anymore. Now, it means anyone with a Caucasian skull structure. Caucasians have deep eye sockets, high cheekbones (just to name a few features) and Caucasian men are also usually more hairy than men of other races.
you have it backwards. the skull stuff is outdated pseudoscience. caucasian started as and still means someone from the caucasus mountains. I don't know if anyone but the US still uses the outdated nomenclature
I think maybe Caucasoid would be a more accurate term.
