Ch 15: Glencoe Biology Chapter 15: Evolution

About This Chapter

The Evolution chapter of this Glencoe Biology companion course helps students learn the essential biology lessons of evolutionary theory and change. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Evolution textbook chapter.

How it works:

  • Identify the lessons in Glencoe Biology's Evolution chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the evolution topics 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:

  • Evidence for evolution
  • Natural selection types and adaptation
  • Predator-prey interactions
  • Camouflage, mimicry and warning coloration
  • Forms of evolutionary change
  • Punctuated equilibria and the molecular clock
  • The Hardy-Weinberg equilibrium
  • Allopatric and sympatric speciation
  • Prezygotic and postzygotic reproductive barriers

Natural Selection & Adaptation: Definition, Theory & Examples

1. 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

2. 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.

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

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.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

4. Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

You probably know that skunks can be quite stinky, bees sting and monarch butterflies are pretty, but do you know why? This lesson will introduce you to the reasons why some animals look or act the way they do and how these things relate to the predator/prey relationship.

Evolutionary Change: Definition and Forms

5. 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.

Rates of Evolution: Punctuated Equilibrium & Molecular Clock Hypothesis

6. 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.

Hardy-Weinberg Equilibrium I: Overview

7. Hardy-Weinberg Equilibrium I: Overview

In this lesson, we'll examine population genetics in greater detail. We'll also explore notions of Hardy-Weinberg equilibrium for large, stable populations. Is the genetic makeup of our flying hamster population changing? The Hardy-Weinberg equilibrium can serve as a reference point as we try to answer population genetics questions.

Speciation: Allopatric and Sympatric Speciation

8. 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

9. 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

10. 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.
