1. describe the kinds of evidence for evolution.
2. Explain how each of the following makes it difficult to clearly define a species: variation within a species, geographically isolated populations, asexual species, fossil organisms.
3. How can the Darwinian concept of descent with modification explain the evolution of such complex structures as an eye?
4. Summarize the hypotheses that explain variation in human skin color as adaptations to variation in UV radiation by explaining why a dark-skinned POPULATION of humans from New Guinea would have lower fitness over time if they moved to a far northern latitude country such as Finland.
