The word used by biologists to describe an environment where individual differences have been sanded down and every organism follows the same path of development is monoculture. Monocultures are rare; the default state for most natural systems is diversity. A monoculture typically emerges only when something happens, deliberate or otherwise, to upset the natural order—for instance, when a group of affluent parents comes together to create a community that perfectly reflects their commitment to achievement and excellence.
