:Evolution is not blind chemistry. It is easy to see how altruism and morality can lead to differential reproductive success on which natural selection can operate. For example, chickens have a pecking order that determines which members of a population get the first chance at food. The members of the population could compete every time there is food, but this would waste energy (possibly more than is contained in the food). Likewise, we humans should be glad that we do not have to fight to get to the cashier in a restaurant, for we have developed queueing. It is also easy to see how altruism develops in a population, since altruism can increase the reproductive success of a population. Any biology student could explain how mutations increasing intelligence are selected for in evolution: in many cases (but not all), greater intellectual capacity can increase reproductive fitness. | :Evolution is not blind chemistry.
