How to Create a Cladogram Worksheet with Answer Key

Begin by identifying the traits that distinguish each organism. These features will serve as the basis for grouping species into categories. Select characteristics that are shared by several species, ensuring they are relevant for comparison.

Organize the species into a hierarchical structure: Start by placing the most general traits at the bottom and gradually move upwards to more specific traits. Each branch of the diagram should split based on shared characteristics, leading to the classification of organisms into distinct groups.

To visualize this: Draw lines connecting the organisms based on their common traits. As you move along the tree, each node represents a branching point where species begin to show different characteristics, thus forming a new classification. Double-check the connections to ensure accuracy, and verify that each organism fits logically within its group.

By following these steps and reviewing examples, you will be able to create a structured diagram that clearly represents the relationships between different species based on shared evolutionary traits.
