Ch 6: Natural Selection & Adaptation in Populations

About This Chapter

Within the field of evolutionary biology, scientists understand that having varied genetic traits can assist in species survival. Whether studying for a test or just coming to a better understanding of these principles, the self-paced lessons in this chapter will be useful and engaging.

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
