Ch 2: ScienceFusion The Diversity of Living Things Unit 1.2: Theory of Evolution by Natural Selection

About This Chapter

The Theory of Evolution by Natural Selection chapter of this ScienceFusion The Diversity of Living Things Companion Course helps students learn the essential lessons associated with the theory of evolution. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Theory of Evolution by Natural Selection textbook chapter.

How It Works:

  • Identify the lessons in the ScienceFusion Theory of Evolution by Natural Selection chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the theory of 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.

Charles Darwin: Voyages, Theories & Works

1. Charles Darwin: Voyages, Theories & Works

In this lesson we explore the life and voyages of the 19th-century British naturalist Charles Darwin and his formulation of the theory of natural selection.

Artificial Selection in Evolution

2. Artificial Selection in Evolution

Humans have been selectively breeding for desirable traits in plants and animals for a long time. This artificial selection allows for a lot of control in the breeding process but can also lead to unintended mutations within a population of organisms.

Theories of Evolution: Lamarck vs. Darwin

3. 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.

Thomas Malthus' Theory of Human Population Growth

4. Thomas Malthus' Theory of Human Population Growth

In this lesson, we will explore the ideas of Thomas Malthus and his predictions for the growth of the human population. We will also investigate if his predictions have come true or not.

How Darwin's Observations Showed the Process of Natural Selection

5. How Darwin's Observations Showed the Process of Natural Selection

In this lesson, we will learn about the observations that led to the development of Darwin's theory of natural selection. We'll explore how natural selection happens and how this brings about genetic diversity.

What Is Genetic Variation? - Sources, Definition & Types

6. What Is Genetic Variation? - Sources, Definition & Types

Natural selection is the process that drives evolution, but what drives natural selection? Genetic variation increases the genetic diversity in and among populations, allowing for new traits to become more or less prominent in the gene pool.

What Is Extinction? - Defining Background and Mass Extinction

7. 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.
