Ch 14: Glencoe Biology Chapter 14: The History of Life

About This Chapter

The History of Life chapter of this Glencoe Biology companion course helps students learn the essential biology lessons of early life on Earth. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the History of Life textbook chapter.

How it works:

  • Identify the lessons in Glencoe Biology's History of Life chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the geological dating methods and theories you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, re-watch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn about:

  • The geologic time scale
  • Relative dating with index fossils
  • Radiometric dating methods
  • Theories on the origin of life on Earth
  • The endosymbiosis theory

Geologic Time Scale: Major Eons, Eras, Periods and Epochs

1. Geologic Time Scale: Major Eons, Eras, Periods and Epochs

The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.

Methods of Geological Dating: Numerical and Relative Dating

2. Methods of Geological Dating: Numerical and Relative Dating

Learn how scientists determine the ages of rocks and fossils. We'll explore both relative and numerical dating on our quest to understand the process of geological dating. Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

Relative Dating with Fossils: Index Fossils as Indicators of Time

3. Relative Dating with Fossils: Index Fossils as Indicators of Time

You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks.

Radiometric Dating: Methods, Uses & the Significance of Half-Life

4. Radiometric Dating: Methods, Uses & the Significance of Half-Life

Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson.

The Origin of Life on Earth: Theories and Explanations

5. 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 Endosymbiosis Theory: Evolution of Cells

6. 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.
