On the Origins of Disease


Course Description

A comparative and evolutionary perspective on the origins and pathogenesis of disease. Topics include: Darwinian medicine, pathology, natural selection and infectious disease, evolution of host defenses, evolutionary models of cancer, selective breeding and disease susceptibility, and relationships between diet and toxins. Diseases of both man and animals will be studied.

Additional Requirements for Graduate Students:
In addition to taking the course exams, graduate students will be required to write a review of a scientific paper using guidelines outlined in the syllabus.
