Evolution is often called the "unifying theory of biology" that links areas such as genetics, molecular biology, and classification. In this unit, students will gain an understanding of the theories of evolution, comparing Darwin with other scientists. They will learn about the process of natural selection and how it is the basis for evolution. They will analyze new and old evidence that has lead to our understanding of how life evolved and how it is evolving. They will gain an understanding for the system of classification and taxonomy.
