Anthropologists Liv Nilsson Stutz and Aaron Jonas Stutz from Emory University found thousands of stone tools from the early Upper Paleolithic, which revealed clues about how humans might have started organizing into more complex social groups by planning tasks and specializing in different technical skills.
