Final answer:
The Neolithic changes leading to domestication and sedentism are attributed primarily to environmental factors and technological advancements.
Step-by-step explanation:
The two primary determinants that best explain the Neolithic changes leading to domestication and sedentism are environmental factors and technological advancements. Environmental factors provided the necessary conditions such as fertile land and suitable climates, while technological advancements included the creation of farming tools and techniques for plant cultivation and animal domestication. Together, these determinants allowed for the emergence of stable, sedentary communities capable of supporting larger populations through surplus production of food. This shift to agriculture brought profound transformations, such as labor specialization and the emergence of hierarchical structures within societies, changing the very fabric of human civilization.
Examples of Neolithic settlements, like Çatalhöyük, feature sophisticated art and architecture, indicating high degrees of cooperation among the people. This period marked a significant transition from hunter-gatherer societies to agricultural settlements that continued to evolve. Structures like these provide insight into the cultural and social evolution that was taking place during this time.
