"It is through multilevel or group-level selection — favoring the survival of one group of organisms over another — that evolution has in Dr. Wilson’s view brought into being the many essential genes that benefit the group at the individual’s expense. In humans, these may include genes that underlie generosity, moral constraints, even religious behavior. Such traits are difficult to account for, though not impossible, on the view that natural selection favors only behaviors that help the individual to survive and leave more children."
