Final answer:
A phylogenetic tree or cladogram is a visualization of the evolutionary history among organisms based on shared characteristics. In this lab activity, you will create a phylogenetic tree with 20 SpongeBob characters and 35 shared derived characteristics of the Animal Kingdom, noting any instances of convergence. Accuracy and clarity are important in constructing the tree.
Step-by-step explanation:
A phylogenetic tree or cladogram is a visual representation of the evolutionary history among a group of organisms based on shared characteristics. In this lab activity, you will create a phylogenetic tree with 20 SpongeBob characters and 35 shared derived characteristics of the Animal Kingdom. A shared derived characteristic is a trait that derived at some point in the evolutionary history and is found only in some of the organisms in the tree. Instances of convergence, which is when unrelated organisms independently evolve similar traits, should also be noted.
Here is an example of how the lab can be structured:
- Create a phylogenetic tree with all 20 SpongeBob characters and place them in the correct positions according to their shared derived characteristics.
- Use all 35 traits/characteristics and clearly describe which character they represent.
- Note any instances of convergence, where different characters show similar traits.
- Make sure the tree is legible, and all names and characters are visible.
Remember, accuracy and clarity are essential in constructing the phylogenetic tree.
