About This Chapter
Natural Selection and Adaptation in Populations - Chapter Summary
Different genetic traits can sometimes be selected due to environmental pressures. Within this chapter, you will learn why this occurs and how to perform calculations to predict the selection of genetic traits. With most lessons taking less than ten minutes, you'll be able to learn with any free time throughout the day. After you've completed the lessons in this chapter, you will be able to:
- Explain what occurs when one population trait is favored as a result of natural selection
- Calculate the rate of adaption in large and small populations
- Provide examples of lineage-specific traits and why changes in these traits are different
- Compare and contrast game theory and evolutionary game theory
- Describe how altruistic behavior contributes to evolutionary success
1. How Natural Selection Affects Populations
Varied genetic traits help species survive changes to their environment. This lesson will explain what happens in a population when one trait is favored over another due to environmental pressures.
2. Game Theory: Examples & Applications
In this lesson, you can explore the concept of game theory. Learn the definition, then take a look at a couple of examples: the prisoner's dilemma and the car-buying process.
