CH. 16. Evidence of Evolution     Objectives :   Key Terms : 1.     Understand the development of evolutionary theory and the struggle to overcome early  beliefs. 2.     Understand the ideas and evidence that biologists use to explain how life might have  changed through time. 3.     Compare and contrast the differing views on how species might have changed and  emerged. 4.     Explain the origin and eventual articulation of the views Darwin had on evolution. 5.     Understand how variation occurs in populations and how changes in allele frequencies          can be measured. 6.     Know how mutations, gene flow, and population size can influence the rate and direction of  population change. 7.     Understand the central role natural selection plays in evolutionary science. 8.     Describe the kinds of selection mechanisms that help shape populations. 9.     Understand how evolutionary evidence helps to classify and establish relationships between  species. Become familiar with cladograms and the information they present.
