Document Summary

Evolutionary medicine (em) = theoretical frameworks of ecology & evolution applied to the study of health and disease. Human ecology: the study of humans as a mammalian species that attempts to achieve its basic biological goals while it interacts (affects and is affected by) its ecological context. Basic biological goals: survival and reproduction, differences in survival and reproduction lead to evolution. A change in the genetic makeup of a population between cohorts. How does is occur: natural selection, genetic drift, gene flow. Natural selection (ns) (process: variation in survivorship, variation in reproduction. Differential reproduction is a consequence of differences among individuals in their ability to survive and reproduces in a given ecological context. Yes: cancer, anxiety/ depression, number of friends we are able to make and maintain. Health and disease can be linked to survival and reproduction.
