Few scientists have been as influential and controversial as Charles Darwin. Darwin’s theory of evolution by natural selection not only reinvented modern biology in all its branches but also rocked theology and religion in ways that resound to this day.
Mother Teresa poses a perennial problem for evolutionary biology. How can one explain her selfless giving when natural selection drives us to be selfish? For the evolutionary biologist, Mother Teresa's actions must be either maladaptive or secretly selfish, and some biologists have argued both points. David Sloan Wilson presents a third alternative.
