BIOL 123: Evolution Virtual Lab
Objectives: Following this lab you should be able to…
- Describe the key mechanisms by which evolution occurs.
- Explain the evidence for evolution via the fossil record, DNA, and biogeography.
- Describe specific examples of evolution case studies, such as the evolution of birds, whales, and humans.
- Discuss and describe human evolution.
Overview
- Exercise I. You will complete a virtual lab through NOVA on evolution. It has three parts followed by construction of phylogenic trees. You will submit four pictures of you working through each exercise and the results of your tree construction in the post-lab.
- Exercise II. You will watch a 19-minute long movie called, Great Transitions: The Origin of Humans. You will create a table of human hominids mentioned in the movie along with important notes in the post-lab.
- Exercise III. You will watch a TedTalk of your choice on evolution. You will share your thoughts in a short essay reflection in the post-lab.
ustrate the evolutionary relationships between Australopithecus and early Hominid fossils by comparing fossil evidence.
You will first need to create a coded character matrix from the character matrix below. Then construct a phylogenetic tree to illustrate the relationships among these taxa.

You will first need to create a coded character matrix from the character matrix below. Then construct a phylogenetic tree to illustrate the relationships among these taxa.
Submit a Word document with the following:
- Coded character Matrix (10 pts): Must be a table create in Word or pasted from Excel.
- Phylogeny (15 pts): The phylogeny can be a picture of your hand-drawn tree pasted into the word document or drawn using any other program or software you choose.

Before you begin! Open the Evolution Post-Lab.
Follow the directions in each exercise closely so you know what to put in your Post-Lab to receive full credit for this online activity.
You will be completing an evolution virtual lab through NOVA LABS. You must complete four parts of this virtual lab.
|
- Watch this 19-minute long movie called, Great Transitions: The Origin of Humans.
- Take notes throughout, paying close attention to: the name of each hominid discussed, the scientist who made the discovery, the age, and any related human characteristics.
- You will be asked to put all this information into a table in the post lab.
- Please visit this page on Evolution Based TedTalks. (https://www.ted.com/playlists/84/ancient_clues)
- You will find 6 different TedTalks about evolution and the origin of humans. Please select one to watch based on your interests!
- You will complete a reflection on your TedTalk in the post lab.
