Ch 25: TExMaT Master Science Teacher 8-12: Biological Evolution

About This Chapter

Get set to take the TExMaT Master Science Teacher 8-12 examination by building upon your understanding of biological evolution. This chapter's video lessons cover the subject in depth to help you prepare for the examination questions.

TExMaT Master Science Teacher 8-12: Biological Evolution - Chapter Summary

This chapter's video lessons explore the evolutionary process while providing examples of adaptation, population genetics and artificial selection. They also aim to improve your ability to solve science equations. While you get ready to take the TExMaT Master Science Teacher 8-12 examination, look to this chapter for assistance with:

  • Understanding genetic variability and the different types of natural selection
  • Describing various kinds of speciation
  • Explaining the adaptation of the peppered moths and discussing the Hardy-Weinberg equation
  • Discussing the punctuated equilibrium hypothesis
  • Explaining and presenting evidence that supports the theory of evolution
  • Providing details about mass extinction

Qualified instructors teach some of the topics you'll need to know to pass the TExMaT Master Science Teacher 8-12 examination. You may study at your own pace and take advantage of the opportunity to submit your questions on biological evolution. Review the topics that you don't recall and skip the subjects you've already mastered. Afterward, express your knowledge when you take the lesson quizzes and the practice chapter examination.

Evolution Theory, Evidence & Rates

1. Evolution Theory, Evidence & Rates

This lesson will briefly introduce the theory of evolution, discuss a few pieces of evidence supporting the theory of evolution, and discuss the rates of evolution.

Forms & Patterns of Evolutionary Change

2. Forms & Patterns of Evolutionary Change

Since Charles Darwin introduced natural selection, scientists have come up with different ideas on how evolution proceeds, and how living things evolve over time. This lesson will focus on different patterns of evolution.

Natural Selection & Adaptation Processes

3. Natural Selection & Adaptation Processes

Through the process of adaptation, natural selection shapes the variety of life that exists around us. This lesson will explore some of the ways this process can take place.

Overview of Speciation Types & Barriers

4. Overview of Speciation Types & Barriers

Have you ever wondered how a new species arises? This lesson will examine speciation, or when a new species forms, as well as barriers that prevent separate species from mating.

Genetic Variability, Random Mutation & Artificial Selection

5. Genetic Variability, Random Mutation & Artificial Selection

In this lesson we will discuss the importance of genetic variability and the role of random mutations. We will also compare the processes of natural and artificial selection.

What Is Extinction? - Defining Background and Mass Extinction

6. 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.

Taxonomy: Classification and Naming of Living Things

7. Taxonomy: Classification and Naming of Living Things

The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.

Cladograms and Phylogenetic Trees: Evolution Classifications

8. 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.
