Evidence Supporting Theory of Evolution

Lesson Objective:  Students will try online activities to understand the process of evolution, the mechanisms governing evolution and the evidence that is in support of evolution.

Tasks:

1.  Answer the questions using the activities at your workstation; click here for assistance online.

2. Try the following online activities.

a.  Go to PBS Evolution and explore the website; riddle of the bones, origin of humankind, what killed the dinosaurs.  When you are finished exploring this site, go to the next step.

b.  Go to Learn Genetics and view how different species can evolve from a common ancestor.

Click on the diagram above to take you to an online tutorial describing how to design and interprete cladograms - What Did T.Rex Taste Like?

Molecules reflect evolutionary divergence. You can see that the greater the evolutionary distance from humans (yellow cladogram), the greater the number of amino acid differences in the vertebrate hemoglobin polypeptide.


c.  Go to Smithsonian Institute to learn more about human evolution. 
Fascinating site!  Click on the picture below and choose human evolution evidence in the menu bar.  Enjoy exploring!
