 
"There are human footprints preserved in volcanic ash at Laetoli, made by a male and female
australopithecine, the ancestors of modern humans, just wandering, walking slowly, side by
side, exploring: the original small hominid steps. And there are human footprints at
Tranquility Base and the Ocean of Storms and Fra Mauro and Hadley Rille and Descartes and
Taurus-Littrow on the moon - truly giant leaps."
Robert J. Sawyer
