His reasoning is not Biblical, though. Man was divided at Babel for trying to challenge God--they were supposed to spread out instead of congregate in one area anyway. Furthermore, the Bible states that man has a common blood and that Gentile, Jew, Greek, Scythian, slave, free, etc. are equal in God's way of seeing things. Bazile extrapolates way too far from the Bible, and thus comes to a bad conclusion. Also, he would have difficulty labeling people in the hazy border regions (such as Central Asia, the Mediterranean, the Middle East, etc.). Plenty of people don't fall easily under the races he mentions (and except for very few people, humans are brown, with reddish and yellowish undertones).
That's all the pigment types we have. All the rest involves percentages of pigment in any given area of skin.
You can tell the guys with the red pigment ~ they have green eyes!
