Cloning Books

“In the thousands of years before European colonists landed in the West, the area that would come to be occupied by the United States and Canada produced only a handful of lasting foods---strawberries, pecans, blueberries, and some squashes---that had the durability to survive millennia. Mexico and South America had a respectable collection, including corn, peppers, beans, tomatoes, potatoes, pineapples, and peanuts. But the list is quaint when compared to what the other side of the world was up to. Early civilizations in Asia and Africa yielded an incalculable bounty: rice, sugar, apples, soy, onions, bananas, wheat, citrus, coconuts, mangoes, and thousands more that endure today.
If domesticating crops was an earth-changing advance, figuring out how to reproduce them came a close second. Edible plants tend to reproduce sexually. A seed produces a plant. The plant produces flowers. The flowers find some form of sperm (i.e., pollen) from other plants. This is nature beautifully at work. But it was inconvenient for long-ago humans who wanted to replicate a specific food they liked. The stroke of genius from early farmers was to realize they could bypass the sexual dance and produce plants vegetatively instead, which is to say, without seeds. Take a small cutting from a mature apple tree, graft it onto mature rootstock, and it'll produce perfectly identical apples. Millenia before humans learned how to clone a sheep, they discovered how to clone plants, and every Granny Smith apple, Bartlett pear, and Cavendish banana you've ever eaten leaves you further indebted to the people who figured that out.
Still, even on the same planet, there were two worlds for almost all of human time. People are believed to have dug the first roots of agriculture in the Middle East, in the so-called Fertile Crescent, which had all the qualities of a farmer's dream: warm climate; rich, airy soil; and two flowing rivers, the Tigris and Euphrates. Around ten thousand years before Jesus walked the earth, humans taught themselves how to grow grains like barley and wheat, and soon after, dates, figs, and pomegranates.”
