Impromptu: Amplifying Our Humanity Through AI stimulated cognitive development and impacted how early humans interacted with each other? GPT-4: The Olduvai Gorge is a site in Tanzania where researchers have found evidence of some of the earli- est stone tool use by hominids, dating back about two million years. This find suggests that early hominids were using tools to butcher animals for food, which likely helped them survive and thrive in their environment. The use of these tools might have stimulated cognitive development, as these early humans would have had to manipulate the stones to make them effective tools, and then use them in strategic ways to extract food from their prey. The use of tools would have required the development of fine motor skills, which generally requires complex brain function. Additionally, the act of using tools to obtain food would have necessitated strategic thinking, problem solving, and planning—all of which are cognitive abilities that would have been bene- ficial to early humans in a variety of ways. It’s difficult to say definitively, but if early humans were using tools to improve their chances of survival, they may have been able to devote more time and resources to social interaction, which could have led to the devel- opment of more complex communication systems and even the formation of larger social groups. Reid: OK, last one. What can you tell me about how the taming of fire changed early humans’ cognitive ability and social interactions? GPT-4: The taming of fire was a huge milestone for early humans. Fire allowed humans to cook food, which changed their diets, as well as stay warm and protect themselves from predators. It also allowed for greater social interaction, as fire could act as a focal point for gatherings. Some researchers have even suggested that 200
