摘要

Analysis of the three most ancient Zea mays inflorescence frag- ments from Guila Naquitz, Oaxaca, Mexico shows they did not disarticulate naturally, indicating that agricultural selection of domesticated teosinte was underway by 5,400 ~14C years before the present (about 4,200 dendrocalibrated years B.C.). The cooccur- rence of two-ranked specimens with two rows and four rows of grain and numerous additional morphological characteristics of these specimens support hypatheses based on molecular and quantitative genetic analyses that maize evolved from teosinte. Domestication of the wild ancestor of maize occurred before the end of the 5th millennium B.C.
