A: The Galapagos Islands.
2. What is one string of evidence that supports the theory of Evolution?
A: Similarities in homologous structures between different species.
3. What is the Fossil Record?
A: It is the sequence in which fossils appear within layers of sedimentary rocks.
Five Main Facts From The Reading:
1.Charles Darwin proposed natural selection as the mechanism of evolution.
2.Scientists can observe natural selection in action.
3.The study of fossils provides strong evidence for evolution.
4.Homologies indicate patterns of descent that can be shown of an evolutionary tree.
5.Populations are the units of evolution.

Ten Key Terms:
1. Evolution - the core theme of biology.
2.Artificial selection - the process by which humans have modified other species by selecting and breeding individuals that possess desired trait.
3.Fossil record - the sequence in which fossils appear within layers of sedimentary rocks-provides some of the strongest evidence of evolution.
4.Biogeography - the geographic distribution of species.
5.Vestigial organs - structures that are of marginal or perhaps no importance to the organism.
6.Population - a group of individuals of the same species living in the same place at the same time.
7.Mutation - a change in the nucleotide sequence of DNA.
8.Genetic drift - a change in the gene pool of a population due to chance.
9.Founder effect - differences in a gene pool of a small colony compared with the original population.
10.Sexual dimorphism - the distinction in appearance.
Summary:
This chapter is all about the theory of evolution: all life on earth is descended from primitive, single-cell life forms. It also covers natural selection, the process in which the organisms most fit for survival in a certain climate are more likely to pass on their genes, while the less-suitable organisms die along with their traits.
