Summary

The huge ears of modern corn look nothing like the ears of teosinte, corn's ancestor. The question is: How did modern corn get that way? As Fedoroff explains in her Perspective, molecular sleuthing reveals that just a few genetic changes in teosinte were sufficient to produce a progenitor of modern corn, which was then carefully selected over thousands of years by our farmer ancestors to produce the corn that we pop in microwaves today ( Jaenicke et al.).
