3. A bit about me.. • From Willmar, Minnesota Weather for Saturday: 2 °

7. First year PhD student in Rebecca Safran’s Lab Study: Sexual Selection, Divergence, Speciation and Parasite Interactions- In Barn Swallows

8. Who are you? Name, year, major, where you are from, interesting fact, coolest animal you have ever seen. (it is a lot but you can handle it)

9. THE COURSE • Classroom Expectations • Lab Manuals • Objectives of Lab • Class Structure • Grading • Quizzes, Lab Reports • Attendance • Honor Code • Resources

10. Laboratory Safety

11. Things to look out for: • Prediction vsHypothesis • Prove • Theory

12. Key Words • Phylogeny: Evolutionary History • Taxonomy: Classifying organisms (organizes them based on phylogeny) • Systematics: Study of diversity of organisms in relation to their phylogeny

15. Carl Linnaeus: What is in a Name Domain Kingdom Phylum Class Order Family Genus Species Dear King Phillip Came Over For Green Socks Genus (noun) Specific name (adjective) Hirundorustica Pinus ponderosa

18. Key Words • Analogy- Similar in structure or function, different evolutionary origins. • Homology- Similar in structure or function due to common ancestry.

20. Analogous Traits Convergent Evolution: Have come up with the same answer from different backgrounds

21. Hand Homology May look different: but have a common ancestor, the same bones used for different things.

22. Today’s Lab • Use Skull characteristics to figure out similarities (aka relatedness) • Build phylogeny • Use DNA to look at similarities • Build phylogeny • Compare

23. Using characteristics to create… • A Character Matrix • A Dissimilarity Matrix

25. Diastema

27. Things to Think About • How do the methods compare? • Why? • Is one better?
