In this science lesson, students look at how animals have traditionally been classified in a tree of life diagram by examining the characteristics of plastic eggs. They then analyze the genetic code assigned for each egg and look for...

The Tree of Life is a multi-authored, Internet distributed project containing information about phylogeny and biodiversity. The Tree of Life can be used to locate information about a particular group of organisms through their taxonomy.

Shape of Life is a series of videos which explore the evolution of the animal kingdom. Discover those who study animals and the methods in which these scientists use to learn more about them.

Learn about the diversity of species on Earth by exploring a cladogram, a graph-like tree of life that illustrates relatedness among species. Includes instructions for reading cladograms and a pie chart that summarizes the percentages of...

The Tree of Life Web Project contains information on living organisms including their history and characteristics. Over 3,000 web pages are linked together uniting all living things.

Scientists look at the evolutionary history of organisms to divide them into kingdoms. For awhile, there has been 5 kingdoms, but many scientist are now using 6 kingdoms.

College-level instructor's notes describing taxonomy. Explanations and images give a chronological history of the science of classifying organisms.

In this biology field investigation, students will investigate the site of an environmental disturbance, identify plant and animal life within that specific area, and compare it to an adjoining forested area. Students will map both areas...
