Without flowers, we would not be.
Michael Pollan, The Botany of Desire
With flowers came fruit and seeds, and these, too, remade life on Earth. By producing sugars and proteins to entice animals to disperse their seed, the angiosperms multiplied the world’s supply of food energy, making possible the rise of large warm-blooded mammals. Without flowers, the reptiles, which had gotten along fine in a leafy, fruitless world, would probably still rule. Without flowers, we would not be. (Ibid.)
