  • Independent Innovation & Cultural Diffusion Independent innovation and cultural diffusion led to adoption of agriculture around the world As societies increased the domestication of animals and plants, techniques were borrowed and handed on Seeds and crops were also exchanged, increasing what was grown and traded Agricultural Advantages: Surplus of food meant more dependable supply More dependable supply meant greater population growth Population growth led to social stratification as societies became more sedentary Specialization of labor and private property are natural results of settled lifestyles Specialization of labor led to more complex and hierarchical social structures
