A pattern of multiple correlated genes isn't 'essentialist'. The term hearkens to the notion of the Platonic ideal that some single quality defines groups. It's one of the standard strawman arguments against human races ('no gene for race', 'racial essence'), and as such its ambiguity and polemic sense is not helpful here. Perhaps if you reference Morning's definition of 'essentialist' and that she demontrates biologists fit the description in their view of human race we may have something to go with. Individuals of a race do not carry an 'essence' (neither do coyotes), thet exhibit similar genetic patterns. 27.1.214.45
