Evolutionary Biology Spring 2016 Study Questions
Lecture 1 - Jan 20th 2015
1) What type of adaptation would you expect to see in an organism living in an environment with visual predators?
2) What’s one possible explanation for powered flight appearing only once in invertebrates and at least three times in vertebrates?
3) Why would it be advantageous for an organism to resemble something else; i.e. a caterpillar that looks like bird droppings or an orchid that smells like carrion?
4) What’s convergence? Can you think of an example we saw in lecture?
5) Do similar traits always evolve because they solve the same challenges? For instance, are bright colors always favored because of their role in getting a mate?
6) In what ways can humans be a source of selection to other organisms?
7) What’s the difference between evolutionary change and plasticity?
