1. Cladogram / Phylogenetic Tree

2. Coevolution
the change of a biological object triggered by the change of a related object

3. Punctuated Equilibrium
Theory in evolution that proposes that most species will show little evolutionary change in their history
Most of the time, organisms are very stable
Rapid changes
Proposed by Stephen Jay Gould

5. Cladogram
Is a diagram used in showing the relationship between organisms

6. Cladogram
Is a diagram used in showing the relationship between organisms

7. Cladogram
Is a diagram used in showing the relationship between organisms

8. How are cladograms constructed?
Organisms are grouped together based on their shared characteristics (trait modified from the ancestral trait).

9. Cladograms are used to…
Organize organisms based on evolutionary relationships (Phylogeny)
In other words, who is related to whom and where did they come from?

30. Cladogram Practice
Using the Table, create a cladogram

32. Independent Practice
To make a cladogram, first look at the animals you are studying and establish characteristics that they share and ones that are unique. Using the table, indicate whether the characteristic is present or not. Based on the table, create a cladogram

Legs
Hair
Opposable Thumbs
Slugs
Catfish
Frog
