Information
Description
What It Is:
This is a cladogram analysis worksheet. Part one involves analyzing a pre-made cladogram showing evolutionary relationships between insects. Students must match descriptions like 'wings' and 'curly antennae' to the appropriate letter on the cladogram. The worksheet also includes definitions of terms like 'cladistics' and 'derived characters.' Part two requires students to create their own cladogram based on a table listing characteristics like 'cells,' 'backbone,' 'legs,' 'hair,' and 'opposable thumbs' for different animals including a slug, catfish, frog, tiger, and human.
Grade Level Suitability:
This worksheet is suitable for high school biology or advanced middle school science (grades 7-12). The concepts of cladograms, evolutionary relationships, and derived characteristics require a solid foundation in biology. The creation of a cladogram requires analytical and critical thinking skills more developed in older students.
Why Use It:
This worksheet helps students understand evolutionary relationships and cladistics. It reinforces the concept of derived characteristics and how they are used to classify organisms. By creating their own cladogram, students develop critical thinking and analytical skills while solidifying their understanding of evolutionary biology.
How to Use It:
First, read the definitions of cladogram, cladistics, and derived characters. Then, analyze the provided cladogram and match the descriptions to the letters on the diagram. Finally, use the provided table to determine which characteristics are present or absent in each animal and create your own cladogram based on this information. Place a (1) in the box if the characteristic is present and a (0) if it is not.
Target Users:
This worksheet is targeted towards high school biology students or advanced middle school students learning about evolution, cladistics, and phylogenetic trees. It is also suitable for teachers looking for a hands-on activity to reinforce these concepts.
