Examine the distribution of body morphology across the phylogenies. Use the terms homology, homoplasy, and convergence to describe the evolution of body form among Archaea and Bacteria. Hint: do all of the rod-shaped organisms form a monophyletic group? How about the cocci? What does this likely mean about the evolution of body morphology?

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species

Use the drop down menus to match each example to the fossil topic discussed then to show how the fossil record gives evidence of evolution
