1. The comparative method is one of our two good tools for testing hypotheses about the function of adaptations. Chapter 8 in your textbook discusses and demonstrates this method.
A. Why might the adaptations of two population diverge evolutionarily?
B. What is convergence? If species just happen to resemble each other by chance, is that convergence?
C. Why might different populations evolve convergent adaptations?
D. Selection would never delete a trait after having built it; would it? Explain your answer.
E. What is the difference between a pseudogene and a gene?
