Students analyze gels to determine parentage in this lesson plan about scientific evidence, investigation, and DNA concepts. The lesson plan includes a pre-activity worksheet, a final individual assessment, and student handouts for...

In this zoology word search, students find 30 words. This is a very difficult puzzle with complicated science vocabulary, but there is a word bank.

Students discuss the contributions of different organisms to our world. In this biology activity, students research countries with limited food supply. They create an improvement plan for a fictitious country assigned to them.

Practice exercise on phylogeny.

This lesson plan involves comparison of amino acids to create a phylogenetic tree of primates. Students will also use other species information to draw conclusions about evolutionary relationships.

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.

Visit the virtual exhibits at this site to learn more about paleontology, the history of the earth, and life on earth. Use the information on this site to understand geology, geologic time, evolution, and phylogeny.

Researchers are considering more recent findings of eukaryotes and their phylogeny. Investigate the insights to understand that there may be more progress found in determining the relationships to other eukaryotes.

This is a lesson to help young scholars understand the phylogeny of organisms and how all organisms are linked in a certain way. By navigating an Internet site, students will learn how organisms are classified.

Find out about Ernst Haeckel, a scientist known for his work with ecology, zoology, and the study of phylogeny.

This is an advanced level review of cladistic theory and methodology. Some sections are very dense but there are useful sections for teachers and students seeking a better understanding of the topic.

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.

A lesson plan where students solve problems by using cladistics to determine phylogenies. Problems require that students determine which characteristics are ancestral or derived by looking at both dinosaurs' remains and primate skulls....

This site contains on-line exhibits including animals, plants, time periods, phylogeny, geology, and evolution. Also, a search is provided at the bottom of the site for more specific information.

Standford University provides interesting biographical and professional information on Stephen Jay Gould and his many contributions to scientific thought, including his efforts to help people see science "As something that is important...

An extensive coverage of the evolutionary history of plants. Click on a topic in the outline and you'll go to a good discussion on this material.

A corner of the University of Arizona's Tree of Life project. This site gives the phylogeny and background of the lamprey in good detail. Very strong research site. Abundant references.

Learn about the characteristics, classification, and phylogeny that make the Phylum Chordata, a distinct animal classification group. See examples and photos of different species of chordates.

A self-directed module on all aspects of biological classifications that covers the species problem, diversity and chaos, cladistics, putting things in groups, and so on.

Interactive animation illustrates how Charles Darwin used his study of finch beaks to explain evolution. A phylogenetic tree diagram shows how the birds' color and beak shape changed over generations.

Discusses many aspects of information pertainingto organism classification. Provides links to other areas in biology as well.

Extensive site that contains much information about the various animal phyla. Each phyla gives photos, common examples, scientific names and references. Collection of 1630 websites about bio-diversity.
