BIO102L: Introduction to Evolutionary Biology and Ecology Lab

Unit 6: Phylogeny and Taxonomy   Identifying organisms’ evolutionary relationships is a critical part of biology; it helps researchers understand species’ developmental and ecological connections to one another.  But there is a science to taxonomy and phylogeny, and the methods through which organisms have been identified and are organized continue to change.  In this unit, you will be able to try your hand at using and constructing cladograms and phylogenies.

Unit 6 Time Advisory
This unit should take you approximately 3 hours to complete.

Unit6 Learning Outcomes
Upon successful completion of this unit, the student will be able to:
- Explain the factors involved in creating phylogenetic trees and cladograms. - Design your own phylogenetic trees and cladograms.
