About This Quiz & Worksheet

Cladograms and phylogenetic trees provide a visual image of the relationships between organisms, and our quiz and worksheet can help ensure that you understand all of the differences between the two. Not only will you have to match terms to the correct definitions, you will also practice interpreting data from actual diagrams.

Quiz & Worksheet Goals

These assessments test your ability to:

  • Decipher information about organisms based on a given cladogram
  • Make sense of data using a phylogenetic tree diagram
  • Spot the correct terms related to clades based on a given definition
