Through genetic analysis in the 1970s, an evolutionary biologist showed that there was a very low percentage of human variation existing among groups seen as racially separate. who was this individual

The answer is Richard Lewontin.

Explanation:

Richard Lewontin is an American evolutionary biologist who's findings regarding race and genetics have set a landmark in understanding human differences. He studied the differences among races by studying the variation in protein types in blood, in this study he found that there was only 15% of variation across races.

According to Lewontin, from a genetic point of view, human populations are very similar to each other; this argument defied the notion of "biological race" and set a precedent for the study of race as a social construct.
