I want to know the answer to the following question:
Who was the author of the first published book classifying humans into distinct races?
All the background I'm provided with is that "The first post-Classical published classification of humans into distinct races seems to be François Bernier's Nouvelle division de la terre par les différents espèces ou races qui l'habitent ("New division of Earth by the different species or races which inhabit it"), published in 1684.". Is that enough to answer the question?
