Things to look out for:
• Prediction vs Hypothesis
• Prove
• Theory
![Page 12: General Biology Lab II EBIO 1240](https://reader033.fdocuments.us/reader033/viewer/2022061503/56816466550346895dd64c72/html5/thumbnails/12.jpg)
Key Words• Phylogeny: Evolutionary History
• Taxonomy: Classifying organisms (organizes them based on phylogeny)
• Systematics: Study of diversity of organisms in relation to their phylogeny

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
![Page 23: General Biology Lab II EBIO 1240](https://reader033.fdocuments.us/reader033/viewer/2022061503/56816466550346895dd64c72/html5/thumbnails/23.jpg)
Using characteristics to create…
• A Character Matrix
• A Dissimilarity Matrix

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