Autoimmune disease is a price of our remarkable ability to attack invaders. Cancer is the price of tissues that can repair themselves. Menopause may protect the interests of our genes in existing children. Even senescence and death are not random, but compromises struck by natural selection as it inexorably shaped out bodies to maximize the transmission of our genes. In such paradoxical benefits, some may find a gentle satisfaction, even a bit of meaning-at least the sort of meaning Dobzhansky recognized. After all, nothing in medicine makes sense except in the light of evolution.

Selection shapes brains that maximize the number of offspring who survive to reproduce themselves. This is very different from maximizing health or longevity. It is also different from maximizing matings. That is why organisms do things other than having sex. Especially humans. Having the most offspring requires allocating plenty of thought and action to getting resources other than mates and matings, especially social resources, such as friends and status. Everyone else is doing the same thing, creating constant conflict, cooperation, and vast social complexity whose comprehension requires a huge brain.

All organisms are shaped to behave in ways that increase fitness even if that decreases health and happiness. Did you ever desperately want to have sex with someone even though you knew that could lead to disaster? Most people have, with sometimes dire consequences. Then there are the rest of our desires and the inevitable suffering because they cannot all be fulfilled. We want so badly to be important, rich, loved, admired, attractive, and powerful. For what? the good feelings from succeeding are just about balanced by the bad feelings from failure. Our emotions benefit our genes far more than they do us.

Long before there were effective treatments, physicians dispensed prognoses, hope, and, above all, meaning. When something terrible happens-and serious disease is always terrible-people want to know why. In a pantheistic world, the explanation was simple - one god had caused the problem, another could cure it. In the time since people have been trying to get along with only one God, explaining disease and evil has become more difficult. Generations of theologians have wrestled with the problem of theodicy-how can a good God allow such bad things to happen to good people? Darwinian medicine can't offer a substitute for such explanations. It can't provide a universe in which events are part of a divine plan, much less one in which individual illness reflects individual sins. It can only show us why we are the way we are, why we are vulnerable to certain diseases.
