The Phylogeny of Play
A deeper understanding of the psychology of human play can be obtained by rehearsing the evolution of play. Its roots can be traced back millions of years; with the passage of time, play behaviors became more complex and more closely attuned to specific behavioral needs. Play reached its apex of complexity in Homo sapiens. Understanding this process reveals important lessons about education and game design. Play is a universal human behavior; every culture engages in some form of culturally defined play. The roots of play stretch far back in time.
