Speciation
______ is a method used to reconstruct relationships among species based on nested sets of shared derived characteristics.
Cladistics
What are the 2 main assumptions when determining how to create a cladogram?
1-speciation is a branching (splitting) process2-the best explanations for evolutionary change are the most parsimonious.
What is the 1st step in making a cladogram?

What is the 2nd step in making a cladogram?
Select characters that vary among species and go to an out-group to compare.
What is the 3rd step in making a cladogram?
Collect information on characters for all taxa.
What is the 4th step in making a cladogram?
Search for the most parsimonious cladogram.
What is a plesiomorphy?
A primitive character
What is a symplesiomorphy?
A shared primitive character.
What is an apomorphy?
