About This Chapter
The Theory of Evolution - Chapter Summary
This chapter focuses on the theory of evolution, including what it is and what types of scientific evidence support it. This chapter is easy to understand, with straightforward definitions and explanations. Topics covered in this chapter include:
- Modern evolutionary synthesis
- Evidence supporting the theory of revolution from different scientific fields
- Rates of evolution
- Genetic variability and random mutation
These lessons are taught by knowledgeable instructors who use an engaging teaching style to ensure a swift and easy learning process. The chapter include text and video lessons as well as quizzes that can help gauge your understanding of the theory of evolution.
1. Theories of Evolution: Lamarck vs. Darwin
We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.
2. Modern Evolutionary Synthesis: Definition & Formation
In this lesson, we will discuss the history of evolutionary theory. We will focus on Darwin and Mendel, discussing why some scientists initially believed these two revolutionaries were incompatible, and how these problems were resolved.
3. Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology
There is much support for the theory of evolution. This evidence comes from a variety of scientific fields and provides information that helps us trace changes in species over time. In this lesson, we'll look at this evidence and explore how it supports the theory of evolution.
4. Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis
In general, evolution is a very long process. But rates of evolution can be different for different organisms. In this video lesson, you will identify how scientists study rates of evolution and fill in some of the missing 'steps' in the fossil record.
5. Genetic Variability and Random Mutation
Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.
