On the first episode of the new Cosmos, Neil Degrasse Tyson mentioned that sex - referring to the biological process of cellular reproduction, minus the bulk of its cultural meaning to us - is as old as early November. That's about 2 billion years ago. And all of humanity, starting with apes? About 5 million years, or starting in the morning on December 31st.
So I wondered, with all that time between the beginning of sex and the beginnings of humanity, when did Play come along? Huizinga's Homo Ludens begins thusly: "Play is older than culture, for culture, however inadequaty defined, always presupposes human society, and animals have not waited for man to teach them their playing. We can safely assert, even, that human civilization has added no essential feature to the general idea of play. Animals play just like men."
Despite this compelling introduction, Huizinga's book is a historical account of play in solely the timeline of human civilization and culture. He accounts for play in the last few thousand years, but before that? When did the animals learn to play? Is play as old as multicellular organisms?
What if it's older than sex?
Maybe it's only as old as consciousness itself. For Huizinga says, "in play, there's always something at play." Perhaps the object of play, whether a concept or a ball, requires a field of consciousness to exist in. Or perhaps play gave rise to consciousness. I'm shooting in the dark here.
Still, it's an interesting question. How old is play? To answer this question would shed light on the nature of play itself.
