What “ethnographic definitions” are you referring to?
The classic Linnaean races are: Mongoloid, Caucasoid, and Negroid.

“Modern” thinking has Africans, Caucasians, East Asians, Oceanian, and Native Americans.

In terms of genetic diversity, there isn’t a pinch of sh!t’s worth of difference between them.

Johann Friedrich Blumenbach (a student of Linneaus’) revised Linneaus’classification system in 1775 when he published “On the Natural Varieties of Mankind.” Blumenbach’s taxonomy includes the Caucasian race or white race; the Mongolian or yellow race; the Malayan or brown race; the Negro, Ethiopian, or black race; and the American or red race.

His Mongolian race included all East Asians and some Central Asians. Blumenbach excluded Southeast Asian islands and Pacific Islanders from his definition as he considered them to be part of the Malay race; and American Indians as he considered them to be part of the American race.

It is Blumenbach’s five race model and not Linneaus’ four race model that has been more widely accepted ever since.
For some interesting reading on the subject “google” “The Geometer of Race” by Stephen Jay Gould and check it out!

Thanks. That was more or less what I was looking for. I don’t think much about race, and so was having trouble selecting good search terms. (I did get a lot of useless info on various marathons, though)...
