Principles of Evolution, Ecology and Behavior (EEB 122)
The lecture presents an overview of evolutionary biology and its two major components, microevolution and macroevolution. The idea of evolution goes back before Darwin, although Darwin thought of natural selection. Evolution is driven by natural selection, the correlation between organism traits and reproductive success, as well as random drift. The history of life goes back approximately 3.7 billion years to a common ancestor, and is marked with key events that affect all life.

Plat 55 is a high durometer silicone that is great for making prototype design and production tooling as well as nests, fixtures, architectural, and artistic molds. It is great for making simple one and two piece molds. The Plat 55 reproduces extremely fine detail. Plat 55 works well for making food grade molds for candy, chocolate, ice, and gelatin. Plat 55 is a platinum base silicone and care must be taken to eliminate the possibility of contamination from items containing tin, sulfur, vinyl, amines, and organotin salts.
