Ancient Farmers Accidentally Bred Aggressive “Warrior” Plants

A new study finds early organized planting favored wheat plants that outcompeted neighbors for light and space.

Over about 1,000–2,000 years, selection promoted structural traits like larger, more vertical leaves in domesticated wheat.

Researchers used a functional-structural plant model and found leaf angle was central to competitive light capture.

Modern breeding has reversed this trend by selecting shorter stems and smaller leaves for managed agriculture.
