      Evolution and Taxonomies                                                 

  At this site three areas are addressed:

  • Philogeny -- the "family tree" of life. Here you will see charts classifying the life forms on earth. You will need to make similar charts for your own planet, abeit on a much more modest scale. If you study these models, constructing your own "family trees" will be easy for you!

  • Geological Time. Studying this branch will help you to understand the immense stretches of time that are involved in the development of life forms. Perhaps you can diagram a similar progression for your own planet. It will give you an idea of more complex forms evolve from simple ones, and how periodic extinctions are followed by a different dominant group.

  • Evolutionary Thought will give you an opportunity to see how scientists are thinking about the development of life.

The Glasgow University Zoology Museum gives descriptions and characteristics of all the land animal phyla.  Short, clear descriptions, helpful pictures and diagrams, and beautifully organized material makes this accessible and interesting reading.
