If you are registered and the course doesn’t appear contact us right away. PHILOSOPHICAL BACKGROUND FOR ECOLOGY AND EVOLUTION: G.E. Hutchinson wrote a book called The Ecological Theatre and The Evolutionary Play . In it, he points out that the drama of evolution is played out in an ecological context. Ecological processes like competition and predation are the mechanisms that drive evolution. The actors in the evolutionary drama are ecological entities (populations). Since all biological processes are ultimately part of evolution, ecology and evolution are intimately intertwined. The ecological interactions of populations, species, communities and ecosystems all have evolutionary consequences. All environmental issues have an ecological basis and both ecological and evolutionary consequences. Global warming, ozone depletion, deforestation, overpopulation, etc. result from the actions and interactions between organisms and their environment. The changed, often impaired, environment, compels all species to adapt to it. This will force all species to change (evolve). Some will thrive and others will go extinct. We must take this seriously since “extinction is forever” . UNIFYING THEMES:

2 Two concepts help unify this course. One is the role of diversity . We will consider many types of diversity from diversity of life, and its evolution during the history of the earth, to genetic diversity (the variety of genotypes in a population or species), which fuels evolution; to species diversity (the variety of species in a natural community), which stabilizes ecosystem processes. Diversity is fundamental to evolution, population biology and ecology. The other unifying concept is spatial and temporal heterogeneity . All systems are variable in space and time. This idea underlies the development of new species, genetic drift, predator-prey
