About This Chapter
TExES Life Science: Biological Evolution - Chapter Summary
This chapter is designed to help you build upon what you've already learned about biological evolution. Through its concise educational video lessons, the chapter allows you to take another look at population genetics and rapid adaptation as well as the process of natural selection. You can also learn more about random mutations and genetic variability as you get set to pass the TExES Life Science examination. Utilize this chapter for help with:
- Understanding the theory of evolution and explaining the evidence that supports it
- Discussing the rate of evolution
- Analyzing Hardy-Weinberg equilibrium and explaining the uses for the equation and evolutionary agents
- Describing the processes and types of natural selection
- Explaining rapid adaptation and the peppered moths
- Understanding the types and processes of speciation
- Defining genetic variability and artificial selection
Delivered by professional educators, the video lessons in this chapter aim to improve your knowledge of these topics. When you watch, you'll find video tags that are useful for quickly locating specific details. Written transcripts of the lessons are also included. Test your knowledge and ensure that you're ready to take the TExES Life Science examination by taking the self-assessment quizzes.
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.
2. Hardy-Weinberg Equilibrium: Definition, Equation & Evolutionary Agents
In this lesson we will define Hardy-Weinberg equilibrium and break down the Hardy-Weinberg equation to figure out if a population of hypothetical beetles is evolving.
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.
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.
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.
