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)
THE COURSE• Classroom Expectations• Lab Manuals• Objectives of Lab• Class Structure• Grading
– Quizzes, Lab Reports• Attendance• Honor Code• Resources
Laboratory Safety
Things to look out for:
• Prediction vs Hypothesis
• Prove
• Theory
Key Words• Phylogeny: Evolutionary History
• Taxonomy: Classifying organisms (organizes them based on phylogeny)
• Systematics: Study of diversity of organisms in relation to their phylogeny
Carl Linnaeus: What is in a Name
1) Genus (noun)2) Specific name (adjective)

Key Words
• Analogy- Similar in structure or function, different evolutionary origins.
• Homology- Similar in structure or function due to common ancestry.
Convergent Evolution: Have come up with the same answer from different backgrounds
Analogous Traits
Hand Homology
May look different: but have a common ancestor, the same bones used for different things.
Today’s Lab• Use Skull characteristics to figure
out similarities (aka relatedness)• Build phylogeny• Use DNA to look at similarities• Build phylogeny• Compare
Using characteristics to create…
• A Character Matrix
• A Dissimilarity Matrix
Diastema
Things to Think About
• How do the methods compare?• Why?• Is one better?
