Hmm, but they've been pulling genetic material from Earth for long enough that diversity in that regard shouldn't be an issue? Plus initial colonies were mixed (pre-current-policies), so I'm unconvinced that the CU would have significantly lower genetic diversity than Earth.
Re 2 -- maybe, but we see that the special forces members who survive get very rapidly very very good, and there's a fair few of them around who could do the leading.
I'm also... unconvinced that the rest of the intelligent species in the area don't know about humanity's home world? Like, they *clearly* failed *utterly* at that.
