Ohio Graduation Test: Evolution - Chapter Summary

Increase your chances of passing the Ohio Graduation Test by getting reacquainted with evolution using the lessons in this chapter. In no time, you will have the knowledge to:

  • Discuss the theory of evolution
  • Describe the scientific evidence that supports evolution
  • Share fossil evidence for biological diversity, mass extinction and speciation and mass extinction
  • Provide details about natural selection and adaption
  • Identify types of natural selection
  • Define allopatric and sympatric speciation
  • Describe prezygotic and postzygotic barriers

All of the lessons in this chapter are short, averaging about 10 minutes each, which makes studying for the test both efficient and effective. Access to prepared lessons allows you to bypass the time-consuming process of compiling and condensing days or weeks of materials. You can prepare for this test by reviewing the lessons in this chapter as videos or full transcripts. Take self-assessment quizzes to determine how prepared you are to answer evolution questions. A chapter exam is also available to reinforce concepts learned in the lessons.

Ohio Graduation Test: Evolution Chapter Objectives

The topics in this chapter on evolution prepare you for questions you'll find on the science portion of the Ohio Graduation Test. This test is one of five total assessments, and it gauges your comprehension of six academic content standards that include earth and space science, life and physical sciences, science and technology, and scientific inquiry.

The Ohio Graduation Tests are required for high school students in the state. They must pass all five tests with minimum scores of 400 each to earn high school diplomas. The science test consists of 32 multiple-choice questions, four short-answer questions and two extended-response questions.

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.

Scientific Evidence That Supports Evolution

2. Scientific Evidence That Supports Evolution

Evolution explains how species that are present on Earth today are modified descendants of their ancestors. This scientific theory is supported by many different types of evidence, which show how evolution is a very real and natural phenomenon.

Fossil Evidence for Biological Diversity, Speciation, & Mass Extinction

3. 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.

Natural Selection & Adaptation: Definition, Theory & Examples

4. Natural Selection & Adaptation: Definition, Theory & Examples

How does natural selection help shape the amazing types of animals we witness around us? In this lesson, we'll explore adaptations and what they can tell us about a species' past evolution.

Natural Selection: Definition, Types & Examples

5. Natural Selection: Definition, Types & Examples

We'll take a look at the types of natural selection that can occur. From flying hamsters to moths, you'll start to grasp the different paths organisms can take as they respond to their changing environments over time.

Speciation: Allopatric and Sympatric Speciation

6. Speciation: Allopatric and Sympatric Speciation

Discover the definition of a species and learn more about how species split. Find out common terms related to the splitting of species and study what role polyploidy plays in the development of a species.

Prezygotic Reproductive Barriers & Speciation: Definition & Examples

7. Prezygotic Reproductive Barriers & Speciation: Definition & Examples

We may take for granted why animals choose to mate with other animals of similar appearance, but it's not that simple. There are actually biological barriers to reproduction that can prevent even seemingly closely related species from reproducing. This lesson looks at one such category of hindrances, prezygotic barriers, which make fertilization impossible.

Postzygotic Reproductive Barriers: Definition & Examples

8. Postzygotic Reproductive Barriers: Definition & Examples

Do flying hamsters represent a separate species from your run-of-the-mill hamsters? We'll get to the bottom of this by performing crosses between the two hamster types. You'll explore postzygotic reproductive barriers and their possibly tragic consequences.
