Almighty God created the races white, black, yellow, malay and red, and he placed them on separate continents. And, but for the interference with his arrangement, there would be no cause for such marriage. The fact that he separated the races shows that he did not intend for the races to mix.
Actually, this is totally contrary to what the Bible says. All the races are descended from Noah, his sons and their wives.
Monogenism is the traditional interpretation, but by the 18th century it became apparent that accepting the literal timeline of Genesis meant that no known natural cause could account for the diversity of peoples in the world. Rather than entertain the notion that the Bible was in error, some chose to develop theories that made it incomplete and focused upon only one particular creation, that which led to the Caucasian race, including the Jews. The other races had originated in their own Edens. Such pangenist theories fell out of fashion once it was realized that the physical evidence indicated that the world had been around considerably longer than the timeline of Genesis would permit if it were taken literally.
