Ch 38: TExES Science 7-12: Theory of Biological Evolution

About This Chapter

Prepare for the Texas Educator Certification Test by using this chapter focused on biological evolution. Passing this test is one of the requirements for becoming certified to teach 7th-12th grade science in Texas.

TExES Science 7-12: Theory of Biological Evolution - Chapter Summary

Use these lessons in preparation for the TExES Science 7-12 examination. The knowledge you gain will help you answer questions on biological evolution that are on this test. The information covered includes the following:

  • Evolution
  • Hardy Weinberg Equilibrium and the use of the equation
  • Rapid adaptation and different kinds of natural selection
  • Sympatric speciation and reproductive barriers
  • Artificial selection, genetic variability and mutation

Each of these scientific concept will be discussed by an individual who is knowledgeable in the specific area. The assessments that are included with the lessons can be used to check your learning as you move through the lessons. The lessons do not have to be completed in order; you are able to choose what you want to study. The videos have interactive timelines that allow you to select the content areas that you wish to watch instead of watching the entire videos.

Theories of Evolution: Lamarck vs. Darwin

1. 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.

Hardy-Weinberg Equilibrium I: Overview

2. 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.

Natural Selection & Adaptation: Definition, Theory & Examples

3. 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.

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.
