About This Chapter

Watch video lessons to learn more about the theories of natural selection and evolution in life science, including the concepts developed by Charles Darwin.

Natural Selection and Evolution in Life Science - Chapter Summary and Learning Objectives

Charles Darwin is well-known for his contributions to the theory of evolution; a key part of that theory includes his observations related to natural selection. In this series of lessons, a life science instructor will provide you with a broad overview of evolutionary theory, and the ideas of natural selection and adaptation. You'll also learn about specialized subsets of evolutionary theory, like microevolution and macroevolution. This chapter is designed to teach you:

  • The key parts of the theory of evolution
  • Charles Darwin's observations and how they support the theory of evolution and the idea of natural selection
  • The role of natural selection in adaptation
  • Characteristics of microevolutionary and macroevolutionary processes

Video Objective
Theory of Evolution Describe the theory of evolution and how it was developed.
How Darwin's Observations Showed the Process of Natural Selection Define the concept of natural selection, and discuss how Charles Darwin's four observations illustrate it; describe how natural selection contributes to genetic diversity.
Natural Selection and Adaptation Describe how the process of natural selection works within the context of adaptation.
Microevolution and Macroevolution: Similarities and Differences Compare and contrast these two types of evolutionary processes.
