Once you get to garb and/or language it's looking more and more like ethnicity. Italians aren't a race on the check box forms, but there's still citizenship and/or heritage.

The computer game experience of designing one's avatar helps kids appreciate the Mr. Potato Head aspects of genomic expression. Permute at will.

We have lots of ways to draw Venn Diagrams, based on a variety of attributes. Midgets could be a race (regardless of skin tone) if we wanted, but we don't want. That's why they say "race is a social construct" because "we" keep changing our minds about what "we" care about. You can't say Latino is a race in recent census forms.

The so-called "races" come and go. In Bible school, they link races to sons of Noah. Those diagrams keep changing as well. Making "Jews" be a race was a project with far more subscribers until recently.

Do people think all native Americans, from Eskimos in the north to descendents of the Incas around Peru, form a single race? Not usually, as that wouldn't be convenient. That would turn too many Mexicans into Indians and we can't have that.

BTW, sickle cell anemia is also endemic around Greece and people of light skin tone (POLST) are afflicted.
