Textbook Question
Chapter 21, Problem 22ESP
Homology can be defined as the presence of common structures because of shared ancestry. Homology can involve genes, proteins, or anatomical structures. As a result of “descent with modification,” many homologous structures have adapted different purposes.
- (a) List three anatomical structures in vertebrates that are homologous but have different functions.
- (b) Is it likely that homologous proteins from different species have the same or similar functions? Explain.
- (c) Under what circumstances might one expect proteins of similar function to not share homology? Would you expect such proteins to be homologous at the level of DNA sequences?
