(20,729 posts)do the selective breeding, somehow that's more natural than if white people do it, i guess.
the original corn was a grass.

Part of maizes monstrosity is that it has been highly bred from a normal grassy ancestor. Corn originates from South and Central America and is the result of Native American breeding thats been going on for thousands of years. Its original ancestor is almost certainly teosinte, an unimpressive little grass that produces a few tiny kernels on an inflorescence that shoots out from the top of the plant. Theres several species of teosinte, including Zea diploperennis, and it can be crossed with maize. In teosinte, the female flowers are at the ends of the shoots and the male flowers shoot out from the sides. In corn, its the opposite. So not only has corn been bred to produce large numbers of large kernels all on a single cob, theres been a sex change as well.
