Race in Dune

[TMA_1]

I think this was mentioned before, but concerning the racial backgrounds, it doesnt seem like 3001 where the races mixed togehter completely into a hodge podge of every race. Instead it seems that after the exploration from terra, races stuck together. I also notice that many of the houses and groups in Dune still have key elements that show their origins. Like the atreides heritage of greek influence. Their name, their lore. Even their physical characteristics sound greek. olive skinned, dark hair, blah blha. Then you have the bene gesserit who's home planet to non bene gesserit members is called Wallach IX. Wallach is a name for a certain northern european race (I think thats the case). Any more info you guys have on this? or speculation?

I think after the Butlerian Jihad, people began to find people of their own kind, and it's stuck.

My belief is that endogamy and exogamy will never become extremely popular/"normal", which could be seen as a good thing (i.e. preservation of heritage) or bad thing (racism). So, I'm not surprised that things are like this in Dune.
