Yeah, Healthline is a source for laymen. That information is provided that way because people won’t know what Y-DNA haplogroup they’re in, but will generally know if they’re considered black. There’s public health research by race too, but again that’s related to social outcomes and data availability.
White people have higher tolerance for lactose, so a milk-heavy diet is worse for other races.
Except the other highly tolerant cluster is West Africans, with smaller ones in places like Pakistan and Arabia.
Even though there is a broad scientific agreement that essentialist and typological conceptions of race are untenable, scientists around the world continue to conceptualize race in widely differing ways. While some researchers continue to use the concept of race to make distinctions among fuzzy sets of traits or observable differences in behavior, others in the scientific community suggest that the idea of race is inherently naive or simplistic. Still others argue that, among humans, race has no taxonomic significance because all living humans belong to the same subspecies, Homo sapiens sapiens.
Despite the fact that races do not exist in the genetic sense, in some cultures racial categories are used as a form of cultural expression or identity, or a means of reflecting shared historical experiences. This is one aspect of the concepts of “ethnicity” or “ancestry”.
I tried to find something from the AMA, but it’s so well established all the recent stuff takes the non-biological nature of race as a granted, and talks more about the ethics of handling the social categories.
