Michael Phelps Clones?

You know how they breed dogs and racehorses by choosing the best parents? I even heard recently that some huge percentage of all racehorses come from the same ancestor. It's crazy and forced evolution, but it seems to work, right?

So, should we do this with Michael Phelps? Maybe he could have a baby with Dara Torres, and she could give birth in the water. If they could just install gills on the kiddo, it'd be unbeatable. And I think that would also mean we'd come full circle, turning back into fish. Cool!
