摘要: For more than a century, scholars have debated hypothetical processes that facilitated initial human settlement and the transition from universal hunting–gathering livelihoods to incipient planting, agriculture, plant domestication. Mixed cultivation of food nonfood species in small areas supplied basic needs for 10000 years, protective pattern against total crop failure. Eventually, farmers prepared larger fields single cultigens mechanical harvesting but produced near monoculture agriculture some global regions. Although allows easier farm management, this may pose risk societies mid‐twenty-first century beyond.
