Title: Unit 1 - Evolution
Course: BIO-182 RTZ

The theory of evolution by natural selection describes a mechanism that explains the diversity of life on Earth. It was not the first such theory. However, his theory was unique because he proposed a mechanism for evolution for which no exceptions have been found – natural selection. First described circa 1850’s, this scientific theory has been supported by findings from many fields in biology.

In this unit, we will examine the theory of evolution by natural selection.  First, by looking at the mechanisms of evolution (chp 21). Next we’ll look at the process of speciation, or how new species emerge (chp 23) and finally, we’ll take a look at the evolutionary relationships between organisms (chp 22). We’ll bridge the units of Evolution and Biodiversity by examining the history of life on earth (chp 25).
