The human baseline, taking the long-historical view, is: eating, sleeping, fucking, fighting. I take (say) 'eating' here to encompass, asi t might be, hunting and gathering stuff to eat; just as I take 'sleeping' to encompass resting more generally--lolling about, staring at the trees.
The big shift-up comes with play. Play inflects these baselines activities in ways that parse culture. Dancing, music, science, poetry: all fucking inflected via play. Sport, games, religion, all fighting inflected via play.
