Homology and Phylogenetic Analysis
OVER ARCHING QUESTIONS:
- What is the origin of all the variation in life forms?
- How do Biologist organize and make sense of all the variation?
- What is my (humans) relationship to all this variation?
STEP ONE OF THE INQUIRY:
- Given what you already know, turn these general questions into a hypothesis with testable predictions.
STEP TWO OF THE INQUIRY:
- Make some accurate, precise and repeatable observations.
Procedures and Directions for Evolution 1 (PRINT and bring to lab #1): Homology_lab_part1.doc
Procedures and Directions for Evolution 2 & 3 (PRINT and bring to lab): 7.8.9.Homology_lab_part2.3.4..doc
STEP THREE OF THE INQUIRY:
- Summarize your observations and relate them to your hypothesis and predictions. Revise your hypothesis if the observations are inconsistent with the original hypothesis.
