Lect 6 Study Questions 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. What kind of rocks do fossils usually form in? What is a good definition of a fossil? What are the limitations and biases of the fossil record? What is mass extinction? Be able to describe the events surrounding the End-Cretaceous mass extinction. What is a phylogeny? Be able to name the parts of a phylogenetic tree and understand what they represent. What is an apomorphy? A synapomorphy? A monoplyletic group? A paraphyletic group? A polyphyletic group? Be able to identify these groups on a phylogenetic tree. What is an outgroup? What do we mean when we say a phylogeny is a hypothesis? What are characters? What is a character state? How can we use radioactivity to tell how old a fossil is? Be able to look at a phylogentic tree and identify sister groups What is a sister group? Why do we prefer the most parsimonious tree?
