Ch 16: OAE - Biology: History of Life

About This Chapter

Each of these video lessons has been designed to get you more comfortable with issues relating to the history of life on Earth. Study up and then further prepare for the OAE Biology exam by trying out our self-assessments.

OAE Biology: History of Life - Chapter Summary

The history of life certainly seems like a vast, overwhelming subject area to try to master. Not so with our fantastic video study guides! Each lesson will help you revisit terms and concepts relating to the development of life on Earth. When you're done studying this chapter in preparation for the OAE Biology exam, you'll be able to:

  • Discuss accepted theories for the origins of life on earth
  • Track the major eras of life on earth and list their traits
  • Describe the endosymbiosis theory and how it explains the evolution of eukaryotic cells
  • Define the different forms of evolutionary change
  • Contrast mass extinction from the more common background extinction
  • Use cladograms and phylogenetic trees to track the evolution of different species

Our awesome instructors have put together these video lessons that combine helpful information with charming animation in order to make test preparation easier. After reviewing the history of life, try out some questions similar to those on the exam in our self-assessment section.

OAE Biology: History of Life Chapter Objectives

For teaching candidates and teachers seeking re-licensure in Ohio, the Ohio Assessments for Educators (OAE) is a required credential. Teachers only need to pass the OAE exam corresponding to the classes they plan on teaching. Secondary school life sciences educators who wish to teach grades 7-12 must score a 220 on a scale of 100 to 300 on the OAE Biology exam in order to be cleared to teach.

The exam consists of five domains, each focused on a different category of biology. The genetics and evolution section, which covers 27% of the 150 questions on the exam, includes questions about the development of life on Earth. You will have three hours to complete the multiple-choice exam. Each question is stand-alone and derived from a set criterion determined by Ohio's New Learning Standards.

The Origin of Life on Earth: Theories and Explanations

1. The Origin of Life on Earth: Theories and Explanations

Ever wonder how living things came from non-living things? We will explore what conditions on early Earth may have created life from non-living items.

The History of Life on Earth: Timeline and Characteristics of Major Eras

2. The History of Life on Earth: Timeline and Characteristics of Major Eras

The Earth is over 4 billion years old. Ever wonder what happened during certain time periods in that large amount of time? We will look at the major eons and eras of Earth's history along with important characteristics of each.

The Endosymbiosis Theory: Evolution of Cells

3. The Endosymbiosis Theory: Evolution of Cells

Ever wonder why some cells are very simple and others are complex with countless organelles to remember? We will look at how simple cells evolved to become more complex cells - as well as evidence to support this.

Evolutionary Change: Definition and Forms

4. Evolutionary Change: Definition and Forms

You've probably heard of Charles Darwin and evolution. We know that evolution is change over time, but here we will look at how these changes may have occurred during Earth's history.

What Is Extinction? - Defining Background and Mass Extinction

5. What Is Extinction? - Defining Background and Mass Extinction

In this lesson you'll discover what the term 'extinction' means as well as learn the two different types of extinction: mass extinction and background extinction. You will also discover how humans contribute to extinction events.

Cladograms and Phylogenetic Trees: Evolution Classifications

6. Cladograms and Phylogenetic Trees: Evolution Classifications

Family trees help show how people are related to each other. Similarly, scientists use cladograms and phylogenetic trees to study the relationships between organisms.
