@Evil Tortie's Mom: R.O.A.C.H.: I actually have a portrait of him hanging right here in front of me on the wall. Also Einstein and Mark Twain. We should do a "What's hanging on the wall by your computer?" photo thing sometime.
Little known fact: Thomas Jefferson was a genetic property rights pirate.
During the Revolutionary War, the American long grain rice crop had been pillaged by English troops, and after the war the remaining stocks of short grained rice did not sell well on the global market.
Italy had tasty and valuable long grain rice, but seed stocks were banned for export, under penalty of death. Jefferson "toured" a northern Italian farm with a jacket made without bottom seams in the pockets. When no one was looking, he simply scooped up handfuls of Italy's genetic property, and dumped the loot in his coat. He was invited down to Rome, but feigned illness and high tailed it back to France. The seed stocks were shipped home, and there you have it.
Thats right, the early American economy, founded on genetic piracy!
Except that the selection criteria are assuming that alternative crops that dont do as well are not worth continuing with. This isnt always the case. What they need is to be paid for the 20 billion-billion in resources being plundered that would other wise build technologically advanced cities for the two billion africans who will soon be living there, and given two seats on a six seat security council so that no once can come along and take what is theirs withouth having to fight the United nations for it. Charcoal bands in the soil retain water and liquid fertilizers longer allowing crops to function at higher temperatures than tose coping with dehydrated clay topsoils.
What about natural selection? Assuming the seed for the next year's crop comes from the current crop, the plants that survive and produce seed are the ones best able to grow in current conditions.
@CSX321: This is farming, not "nature." So there is no system of natural selection at work - these farmers are working with strains of maize developed for the immediate climate. And they need crops for the following year. No time to wait for their current strain to evolve, if indeed it evolves at all and doesn't just die out. They need new strains that are easily available in neighboring countries.
@Annalee Newitz: Yes, I'm familiar with farming, living in the heart of the Midwest and having a father who worked for the Department of Agriculture for over 30 years.
I meant to imply that cultivation of selected crops (which is, after all, what crop farming is) has been working pretty well for several thousand years. I expect it will continue to work pretty well. It's not evolution, but simple varietal seed selection, which doesn't necessarily take more than one year.
@CSX321: I guess what I'm trying to say is that since the climate is likely to change from year to year, the seeds that survived last year may not work the following year.

Thomas Jefferson was a pretty cool dude, other than the slave thing.
