  1. Section 3 Evolution in Action Chapter 15 Objectives • Describehow convergent evolution can result among different species. • Explainhow divergent evolution can lead to species diversity. • Compareartificial selection and natural selection. • Explainhow organisms can undergo coevolution.

  2. Section 3 Evolution in Action Chapter 15 Case Study: Caribbean Anole Lizards • Ongoing examples of evolution among living organisms can be observed, recorded, and tested. • In convergent evolution,organisms that are not closely related resemble each other because they have responded to similar environments.

  3. Section 3 Evolution in Action Chapter 15 Case Study: Caribbean Anole Lizards, continued • Divergence and Radiation • In divergent evolution, related populations become less similar as they respond to different environments. • Adaptive radiation is the divergent evolution of a single group of organisms in a new environment.

  4. Section 3 Evolution in Action Chapter 15 Natural Selection of Anole Lizard Species

  5. Section 3 Evolution in Action Chapter 15 Artificial Selection • The great variety of dog breeds is an example ofartificial selection.

  6. Section 3 Evolution in Action Chapter 15 Coevolution • The increasing occurrence of antibiotic resistance among bacteria is an example of coevolution in progress.
