Friday/Monday, October 6/9, 2017 Your Learning Goal: SWBAT compare relationships between species to place them on a modified family tree called a cladogram. Table of Contents: Lines of Descent - 9R+L Key Terms: Related, Common Descent, Cladogram Catalyst: (9L) 1. What do the zebra and the horse have in common? 2. Are the zebra and horse related? 3. What is your evidence? Agenda: Homework: 1. Catalyst 2. Cladogram Building 3. Jigsaw Reading

1. What do the zebra and the horse have in common? 2. Are the zebra and horse related? 3. What is your evidence? 9L
Focus question How can a model help us understand the relationships among organisms?
What observations can we make about the relationships on this family tree?
What does this family tree do well? What can we NOT learn from this tree?
Glossary Related: Connected by a common ancestor(s)

Classification Cards Sort the cards into groups that you think represent close relationships.
Create A List 9R What PHYSICAL CHARACTERISTICS do each of these animals have
Let s Organize create your own species family tree
1. What are some things we can learn from the cladogram? 2. What are some limitations? Organism Relationship Shared Characteristic
Glossary Related: Connected by a common ancestor(s) Cladogram: A tree diagram to show evolutionary relationships based on shared characteristics.
Glossary Related: Connected by a common ancestor(s) Cladogram: A tree diagram to show evolutionary relationships based on shared characteristics. Common Descent: Groups of organisms who share a common ancestor. The theory states all living things came from one original common ancestor.
Putting it Together 1. Read your assigned page as a table group: Do you understand evolutionary Trees? 2. Synthesize your learning into ONE detailed summary sentence (in your own words). 3. Email me your sentence: maxime.salzburg@larchmontcharter.org 9R

How Does our Thinking Change? Where would we put the dolphin on our cladogram? What evidence do we use to make this decision? Add dolphin to your notebook grid and list its physical characteristics
Are Dolphins Mammals? Place dolphin on your cladogram
