The book of Genesis mentions three of Adam and Eve's children: Cain, Abel and Seth.
But geneticists, by tracing the DNA patterns found in people throughout the world, have now identified lineages descended from 10 sons of a genetic Adam and 18 daughters of Eve.
How is this affected by the fact that we are all descended more directly from Noah's family than Adam and Eve? Of course their genes come down through Noah's family but the emphasis on Adam and Eve suggests the bottleneck isn't taken into account.

What I don't get about this whole discussion is why it isn't obvious that any group of living things, from plants to animals to human beings, develops its own limited gene pool when it becomes isolated from the rest of the population. This is what "races" are in any Species. Domestic breeding is an example of how it happens artificially by human choice: you get all the interesting breeds by isolating the genes/alleles that underlie their own peculiar characteristics, keeping them from interbreeding with other breeds of the same Species. Human beings become races simply by forming their own isolated groups and inbreeding among themselves for many generations. Sometimes a breed or race or variety of animals or plants becomes genetically incapable of interbreeding with others of their Species after being genetically reduced and isolated, but that has never happened with human races where interbreeding has always remained possible.

Re: Skin colour
A consensus consequently developed among anthropologists and geneticists that race as the previous generation had known it — as largely discrete, geographically distinct, gene pools — did not exist."
But that's what race IS, genetically speaking. You don't get particular characteristics without the specific genetic combinations that produce them, and where people have become geographically isolated in their migrations and spend generations inbreeding among themselves you're going to get exactly those "largely discrete, geographically distinct, gene pools" that underlie the identifiable traits of each isolated group.
