5 Multiple Choice Questions
- study of fossils and the history of life, ancient climates, and environments
- example of genetic drift where rare alleles or combinations occur i higher frequency in a population isolated from the general population; due to founding individuals containing a fraction of total genetic diversity; ex: dwarfism
- gradualistic: speciation occurs after populations become isolated, each group continuing slowly on its own evolutionary pathway, gradually gives rise to 2 separate species. punctuated: explain the pace of evolution

5 True/False Questions
Adaptation → a change in the sequence of nucleotides in the gene (DNA)
4 main types of anatomical evidence → homologous structures, analogous structures, vestigial structures, embryological development
Mutation → all of the members of a single species occupying a certain area at the same time
Natural Selection: moth example → industrial melanism: prior to industrial revolution, light moths were more common. after the increase in pollution, dark became more popular. once there were pollution regulations, light moths became more popular again
2 main things that result in genetic variety in offspring → why the coastlines of several continents are mirror images, unique distribution patterns of several fossils, why some fossils are found on different continents, why aus., s. america, & africa have distinctive mammels
