Ongoing human evolution could explain recent rise in certain disorders
Date:1/11/2010

selection still influences our biology, despite advances in modern culture and medicine. Stearns found that natural selection favors heavier women and reduces the age at which a woman has her first child.

In the final presentation of the colloquium, researchers called for the integration of evolutionary perspectives into medical school curricula, to help future physicians consider health problems from an evolutionary perspective.

"We're trying to design ways to educate physicians who will have a broader perspective and not think of the human body as a perfectly designed machine," says Ellison. "Our biology is the result of many of evolutionary trade-offs, and understanding these histories and conflicts can really help the physician understand why we get sick and what we might do to stay healthy."

Previous work in evolutionary medicine helped explain why disease is so prevalent and difficult to prevent because natural selection favors reproduction over health, biology evolves more slowly than culture, and pathogens evolve more quickly than humans.

"I think that the main take-home point is that evolution and medicine really do have things to say to each other, and some of these insights actually reduce suffering and save lives," says Stearns.
