Baby Bubbah to the boogie da bang
Gerald Crabtree, a neurobiologist at Stanford University, states that intelligent human behavior requires between 2,000 and 5,000 genes to work together. A mutation or other fault in any of these genes, and some kind of intellectual deficiency results. Before the creation of complex societies, humans suffering from these mutations would have died. But modern societies may have allowed the more intelligent to care for the less intelligent. While anyone who had participated in a group project understands this phenomena, it doesn’t explain why IQ and other tests have consistently risen, and why people with high scores on those tests still do stupid things.
