We are two college professors at Austin College in Sherman, TX who teach about diet, health, and evolution.  Our goal in writing the Hunter-Gatherer Within: Health and the Natural Human Diet was to help our students and people in general to understand the connections between diet, genetics, evolution, and health.  The book has been published by the non-profit scientific research and education organization, The Botanical Research Institute of Texas.
