Maize Domestication Pushed Back 1200 Years

Post by Minimalist »

http://www.sciencedaily.com/releases/20 ... 212037.htm
Maize was domesticated from its wild ancestor more than 8700 years according to biological evidence uncovered by researchers in the Mexico's Central Balsas River Valley. This is the earliest dated evidence -- by 1200 years -- for the presence and use of domesticated maize.

Oddly, I was just reading in Mann's 1491 about the domestication of maize (corn) and it was not a simple process like noting that certain types of wheat or barley could be grown in one field. Maize required some actual bioengineering and it is simply inconceivable that primitive hunter/gatherers could have figured it out. Perhaps they were more advanced than we give them credit for?
Something is wrong here. War, disease, death, destruction, hunger, filth, poverty, torture, crime, corruption, and the Ice Capades. Something is definitely wrong. This is not good work. If this is the best God can do, I am not impressed.

Care to elaborate on the bioengineering?

Laymen's terms Please. :wink:

How about if I just quote Mann instead of trying to paraphrase?
The ancestors of wheat, rice, millet, and barley look like their domesticated descendants; because they are both edible and highly productive, one can easily imagine how the idea of planting them for food came up. Maize can't reproduce itself, because its kernels are securely wrapped in the husk, so Indians must have developed it from some other species. But there are no wild species that resemble maize. It's closest genetic relative is a mountain grass called teosinte that looks strikingly different--for one thing, its "ears" are smaller than baby corn served in Chinese restaurants. No one eats teosinte, because it produces too little grain to be worth harvesting. In creating modern maize from this unpromising plant, Indians performed a feat so improbable that archaeologists and biologists have argued for decades over how it was achieved.

Being a non-scientist but (former) vegetable gardener I can easily answer that.

They found some larger species of Teosinte that since been extirpated.

They found a freak mutation of an existing Teosinte.

I guess the 'scientists' want evidence.

Evidence?

We don' need no stinkin' evidence.
