Global trade has considerably accelerated biological invasions. The annual tropical teosintes, maize closest wild relatives, were recently reported as new agricultural weeds in two European countries, Spain and France. Their prompt settlement under climatic conditions differing drastically from that of their native range indicates rapid genetic evolution. We performed a phenotypic comparison of French and Mexican teosintes under European conditions, and showed that only the former could complete their life cycle during maize cropping season. To test the hypothesis that crop-to-wild introgression
