The impulse to dance existed long before our primate ancestors evolved into humans. Evolutionary biologists suggest that dance was used by early humans to promote the social cooperation essential for our survival. Yet dance could not save this photograph from time. Encased within the time-worn edges of a red wooden frame lies a sun-faded group photograph of a dutch gymnastics team, with a few of them all but erased by the passage of time. Let’s hope that their daily exercise provided them with a resilience that this photograph did not.
