— Neil deGrasse Tyson, Cosmos: A Spacetime Odyssey (Ep 2: Some of the Things that Molecules Do)
"Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life."
