Well because humans are sinful and want to immediately start figuring out who has the most blood of ‘the’ Adam I have already encountered some of this. This even though I made a point to say otherwise in the book. I actually had to go back in a later edition and edit the book to make the point even more emphatically. And I made this video on the subject…
But humans being what they are, even a sequential view of the text can be used to racist ends if that is what people want to do. After all a recent de-Novo Adam would still presumably be missing the genes from any ancient admixture from other hominids. But as I point out at the end of the book, the northern Europeans who have historically been the center of this sort of thing would actually have a SMALLER proportion of heritage from Adam than a lot of other people.
