Eugenics/Designer-babies... is the concept really that bad?

I was under the impression that there's no way an animal as large as a mammal could be adapted to live on a planet like mars.

Googling the subject it says mars is a radiation blasted toxic wasteland.

The only kind of thing I could imagine is a sci fi style, brain adapted to be inside some sort of solar powered machine.  I can imagine we'd end up looking like those spider creatures from the doom computer game.

Well I was thinking more along the lines of giant space cockroaches, but spiders can work just as well I guess, but whatever that form may be, it'd certainly be a whole lot different from adaptations on a water planet or gas planet. So the diversity still will be there and will actually increase.

@Astonished: yeh but the kryptonians were stupidly stuck on a single planet... if they were to spread across the universe of course there'd be some diversity and evolution would continue. I imagine the son of superman is a tiny bit different from his dad, who in turn is different from his dad...
