Final answer:
Modern human behavior is indicated by archaeological evidence such as butchered animal bones, specialized food preparation artifacts, and organized waste disposal. This evidence demonstrates advances in tool use, crafting, and community organization.
Step-by-step explanation:
Three features of the archaeological record that indicate modern human behavior are butchered animal bones, artifacts associated with food preparation such as pottery and stone tools, and organized waste disposal sites like garbage dumps or shell middens. Butchered animal bones show evidence of hunting, skinning, and consumption practices, which are hallmarks of advanced tool use and complex behavior. Pottery and tools used for food processing are indicative of advancements in crafting specialized items for specific purposes, a key aspect of modern human culture. Lastly, the presence of waste disposal sites represents a structured approach to sanitation and community living, further underscoring the development of modern human societies.
