1.   Imagine that you are a medical doctor, and are in practice to maintain the health of your human patients.  However, you begin to wonder if the fact that throughout the great majority of our evolutionary history we lived in very different environmental conditions (i.e., 200,000 years ago to 10,000 years ago) than now could have resulted in mal-adapted bodies for our modern world.  Work on a list of potential medical problems that you think might be due to the fact we are adapted to live in the stone ages, yet live in a technological modern world.  Answer this question using references and information you can find on the WWW by searching for Darwinian Medicine.
