Their DNA evolved in 3 generations? Doesn't really make sense.

You could argue that a small portion of the population happened to already be immune to the radiation, and they continued on.

But then having the Ark people immune as well (due to space radiation or something) doesn't make sense because it would mean a majority of them had to die on the ark.
