Teosinte Comparison

Caption

Corn's wild ancestor, teosinte, is shown growing under modern (chamber on the left) and under past (chamber on the right) climate conditions. Smithsonian scientists Dolores Piperno (right) and Irene Holst (left) with Klaus Winter and Owen McMillan (not shown) wondered if teosinte might show phenotypic plasticity -- change its growth form -- when exposed to different environmental conditions.
