Actually, what came up on google was a blurb, possibly a cover blurb, for some rip-off-of-Tolkein book that I wouldn't bother with; but, hey, it's about as "scientific" as the classification that was (so far as my experience indicates) universally accepted for any number of lifetimes.

One of the lamest pieces of garbage I've seen was a white supremest publication explaining that "Western European Man" is descended from the Cromagnon (sp?) and all other so-called humans are descended from the Neandrathal.
