• Diffusion dates: Europe (~5500), China (~8000 BC), Africa (~8000 BC), Americas (~5000 BC), New Guinea (~7000 BC).
• Early cultivation techniques involved domestication and selective breeding.
• Agriculture led to population growth and complex societies.
• Spread facilitated by trade routes, migration, and cultural exchanges.
• Key regions: Fertile Crescent, China, Africa, Mesoamerica, Andes, New Guinea.
