Earlier quoted context omitted.
"Humans do not have biological race" is correct if and only if you change the definition of "race" to whatever definition these academics have made up expressly to make the statement true. If you use any definition that wasn't specifically concocted to make the statement true (i.e. any definition used by normal people or by actual scientists doing real work, say prior to 1990), it remains false.
What is the implication here, that geneticists decided in 1990 to pack in "real work" in order to work up a grand conspiracy to wipe out an entire concept?
"I'm just studying why people whose ancestors grew up in one area are more likely to have a certain gene than people whose ancestors grew up in a different area. It has absolutely nothing to do with race".
