h the great diversity of microorganisms and their biological, ecological and economic impacts on life and human society.

Click the diagram of the three domains, and then follow to the Systematics link for a group you desire to begin researching for this lab. 2. Visit a number of websites (a few starters are listed below) that deal with the great diversity of microorganisms and their biological, ecological and economic impacts on life and human society. Gather (and cite!) information and images to allow you to prepare a poster or PowerPoint presentation. 3. In your poster or PowerPoint presentation, you will need to detail the classification of the group of creatures you are detailing. 4. Required elements include: the time of first occurrence, fossil record (if any), economic and societal impact of the group, and its evolutionary importance (for example the green algae are not terribly important save as a stem group for the evolution of plants).

Tree of Life Web Project. Maintained by scientists and collaborators, this site organizes over 5000 web pages about the classification and relationships of the domains and other taxonomic groups.
