Okay @
Blanco Bishop i'm about to play devils advocate in this thread a little since you indulged...
In what way is it not "plausible"?
I could argue that we do, already, select for beauty in our mating partners. And we do select for intelligence. Now, I may or may not be defining beauty as inner beauty, or emotional suitability as a spouse. I may or may not be defining intelligence as "gaming the system", for example people like Kim Kardashian do know how to earn a very good living, without building rockets or curing cancer in the garage. But the human race has pretty much been getting just what it wants, one baby step a generation, just like all other sexually reproducing species.
This is happening via natural selection, all around us, right now and has been for years.
Are we not already "selectively" breeding in a sense?
