Get Phylogenetic Tree Worksheet

The Phylogenetic Tree Worksheet is a valuable tool for understanding the relationships between different organisms based on shared traits. This guide provides a clear, step-by-step approach to completing the worksheet effectively online.

Follow the steps to fill out the Phylogenetic Tree Worksheet appropriately.

1. Press the ‘Get Form’ button to access the Phylogenetic Tree Worksheet and open it in your preferred editor.
2. In the first section, you will find a table with various traits like 'cells,' 'legs,' '6 legs,' and 'wings.' Mark an 'X' in the box next to each organism if they possess the corresponding trait. The organisms to evaluate are worm, spider, carpenter ant, and fly.
3. Next, you will see a blank cladogram. Add each of the organisms listed (worm, spider, ant, fly) to the cladogram in positions that reflect their evolutionary relationships based on the traits you identified in the first step.
4. In complete sentences, explain your reasoning for the placement of each organism on the cladogram. This will help clarify your thought process and understanding of evolutionary relationships.
5. On the cladogram, add the traits that differentiate the organisms from each other. This could include unique physical characteristics or behaviors.
6. Analyze your cladogram to determine which two species are more closely related: worms and spiders or spiders and ants. Provide justification for your answer based on the traits depicted.
7. Next, identify the species to which flies are most closely related according to your cladogram and explain your reasoning.
8. Proceed to the next section to fill out another table, which includes traits like 'hair,' 'legs,' 'no tail,' and 'eyes.' Again, mark an 'X' for each organism (human, snake, monkey, lizard) that possesses the respective trait.
9. Similarly, add each of the organisms (human, snake, monkey, lizard) to a new cladogram and reflect on their relationships based on the traits you have noted.
10. Using complete sentences, describe why each organism was positioned where it is on the new cladogram.
11. Add traits to this cladogram to highlight differences among the species listed.
12. Determine which two species are more closely related: humans or snakes, or humans or monkeys, and explain your reasoning.
13. Finally, evaluate the cladogram to identify to which species humans are most closely related and articulate your rationale.
14. After completing the worksheet, ensure you save your changes. You may choose to download, print, or share the completed Phylogenetic Tree Worksheet as needed.
