How do you think climate change during the Neolithic period affected early humans? Check all that apply. Some early humans moved to new areas that were no longer covered in snow and ice. Some early humans stayed in the same areas because new land was unfamiliar. Animals moved to new areas, so some early humans followed them to continue hunting. New plants became available to early humans in areas where snow had melted. Some plants and animals did not survive climate change, causing humans’ food supply to decrease. Increased temperatures made the growing season longer, so early humans had more food.
