From The Atlantic article The Science of Success (h/t, reader):
Most of us have genes that make us as hardy as dandelions: able to take root and survive almost anywhere. A few of us, however, are more like the orchid: fragile and fickle, but capable of blooming spectacularly if given greenhouse care. So holds a provocative new theory of genetics, which asserts that the very genes that give us the most trouble as a species, causing behaviors that are self-destructive and antisocial, also underlie humankindís phenomenal adaptability and evolutionary success. With a bad environment and poor parenting, orchid children can end up depressed, drug-addicted, or in jailóbut with the right environment and good parenting, they can grow up to be societyís most creative, successful, and happy people.
It's an interesting article about the interaction of genes and the environment in primates, but I'm not sure what's so new about it: I thought it was fairly well accepted that variation in personality and behavioral tendencies, like any genetic variations in any species, enhance the adaptability of that species.
