Social interaction and teamwork lead to human intelligence
Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation and teamwork, shedding new light on the origins of what it means to be human.
The idea that social interactions underlie the evolution of intelligence has been around since the mid-70s, but support for this hypothesis has come largely from correlative studies where large brains were observed in more social animals. The authors of the current research provide the first evidence that mechanistically links decision making in social interactions with the evolution of intelligence.
