Ancient Farmers' Practices Led to Evolution of Aggressive 'Warrior' Wheat
Recent research has revealed that the domestication of wheat was significantly influenced by an evolutionary struggle for light and space, leading to the development of aggressive 'warrior' traits in early wheat varieties. The study, conducted by Dr. Yixiang Shan and Professor Colin Osborne from the University of Sheffield, along with collaborators from other universities, found that early farming practices favored wheat plants that could outgrow and outcompete their neighbors. This competitive environment, created by organized planting in fields, led to the emergence of wheat varieties with traits such as larger leaves and more upright growth, which allowed them to capture more sunlight and dominate other plants. The findings, published in Current Biology, highlight how these traits were advantageous in ancient agricultural settings but are less beneficial in modern farming, where cooperation among crops is more desirable.
