aquinasfan, you should have said "who survived, the s or the Jews"
in this case, they both do.
in the specific case you were relating it to however, the Jews did not survive on their own merits alone, nor would they have. the genocide in that region was prevented by the War, an outside action.
Jews are still around. Hitler isn't and hasn't been for some time. Let me think about this for a moment.
What would you have answered in 1944? What would evolutionary theory have had to say then?
At what time do you determine that a group has survived and another hasn't?
Which group is more "fit"?
Invalid comparison of a group to an individual. Groups tend to last longer than individuals.
In 1944, Hitler had lasted longer than 6 million Jews. But why don't we say, for the sake of argument, that the Aryans had lasted longer than the Jews.
Groups can sustain themselves by having the members reproduce. Individals don't do that.
Define 'group.' Define 'species.'
