Actually, "Caucasoid" is a broad geographico-ethnic category that includes many people (not just Whites). The original Caucasoids were Central Asians, Semites and Eastern Europeans near Central Asia. Typical "Caucasoid" features include tan-to-light brown skin, wavy-to-curly hair, big jutting noses, rounded eyes and the ability to grow thick beards.
Western Europeans are just barely "Caucasoid" (they are only in that group due to their relation to Eastern Europeans and South Russians), and were the last Caucasoid group on earth to form.
"Negroid" (the nuanced term is "Congoid") is also a large group that includes people who are not "Black" (like Afro-Asiatics "Hamites" and the North African Berbers and Ethiopoids). Same with "Mongoloid".
