New Light on the Origin of Maize.

How the ear of maize with hundreds of naked kernels borne in pairs on a solid rachis covered by husks derived from the shattering teosinte spike of 7-9 grains encased inhard seed coats has perplexed botanists for many years. There are currently two prominent hypotheses to explain the origin of maize. One claims that teosinte (Zea mays spp. parviglumis) from the Rio Balsas region of Guerrero, Mexico is the progenitor of maize. The other one claims that maize derived from human selection and cultivation of natural recombinants between diploid perennial teosinte (Zea diploperennis) and Tripsacum. This paper will review the two hypotheses in light of new evidence from the sequencing of the maize genome and from recent archaeological investigations in the Rio Balsas.
