Ch 8: OAE Earth & Space Science: Theory of Evolution

About This Chapter

Use the video lessons in this chapter to get up to speed on the theory of evolution. After you've reviewed the information, you could be ready to correctly answer related questions on the OAE Earth and Space Science examination.

OAE Earth and Space Science: Theory of Evolution - Chapter Summary

These video lessons explore various aspects of human and animal evolution. In addition to reviewing evolutionary theories, you'll have opportunities to look at some of the ways in which populations evolve. Discover what scientists have learned about human history from fossils, and brush up on your knowledge of biogeography as you get set to answer relevant OAE Earth and Space Science examination questions. Watch this chapter's online video lessons for assistance with:

  • Explaining the theory of acquired characteristics as well as the correlation between the environment and population genetics
  • Understanding more about paleontology, comparative anatomy and molecular biology
  • Discussing the rates of evolution for different organisms
  • Identifying information that can be gained from fossil evidence
  • Understanding the evolution of humans

Explore and review these topics with the help of the instructional videos and the experienced educators who lead them. All you need is access to the Internet. The videos are self-paced, so you can prepare for the OAE Earth and Space Science examination at your convenience. Use the video tags to find information quickly. You can also submit your questions on the theory of evolution. Self-assessment quizzes measure how much you remember about these topics.

OAE Earth and Space Science: Theory of Evolution - Chapter Objectives

The Geology domain of the OAE Earth and Space Science examination is where you'll apply your understanding of this chapter's topics. This domain is worth 25% of the assessment score. The test as a whole consists of 150 multiple-choice questions. You will have up to 180 minutes to finish this computer-administered examination.

Theories of Evolution: Lamarck vs. Darwin

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.

Evidence for Evolution: Paleontology, Biogeography, Embryology, Comparative Anatomy & Molecular Biology

2. 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.

Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis

3. 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.

Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction

4. Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction

One of the best sources of evidence we have for evolution is the fossil record. Fossils provide a wealth of information on how species change over time and for exciting events like mass extinctions and new species formation.

The Human Fossil Record & Human Evolution

5. The Human Fossil Record & Human Evolution

Fossils can help tell the story of how we evolved. This lesson sheds light on our closest relatives from the past and what traits human beings have developed over time. You'll learn about those species that are extinct but who live on in our genes.
