So to call the process by which other hunter-gatherer groups started farming and specializing and forming civilizations and colonizing until they became you and me "evolution" is a gross misuse of the term. It's sure as hell not genetic evolution, at least. People who farm don't dominate the world because there's a "farm gene" that has become prevalent, but because farmers had more children and they taught those children to farm. Farmers having more kids is NOT "survival of the fittest" in the Darwinian sense; if you raise one of those kids in a hunter-gatherer society, they're not going to spontaneously plant a garden.

Mating with a square-jawed broad-shouldered dude who carries genes for asthma and has no malaria resistance is no way to ensure "quality" genes. That'll just get you a bunch of square-jawed broad-shouldered kids with asthma and malaria.</q>
