• An evolutionary “arms race” for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. • Yixiang Shan and Professor Colin Osborne, in collaboration with the Autonomous University of Madrid and King Juan Carlos University and Wageningen University, examined how wild plants adapted to human exploitation, finding that early cultivation selected for plants with a significantly stronger competitive ability than their wild ancestors.
Article Summaries:
- New research shows that the earliest stages of wheat domestication unintentionally selected for plants with a markedly stronger competitive edge than their wild relatives. Dr. Yixiang Shan and Prof. Colin Osborne, working with the Autonomous University of Madrid, King Juan Carlos University, and Wageningen University, analyzed how human cultivation pressures drove an evolutionary “arms race” for light and space. Their findings suggest that early farmers favored wheat varieties that could outcompete neighbors, a trait that may inform modern crop‑design strategies aimed at improving yield and resilience.
