- What is a cladogram? A cladogram is a diagram that shows relations among organisms. A cladogram uses lines that branch to end at groups of organisms with a common ancestor. The image shows the relationship among groups A, B, and C. Closely related organisms will have one or more SHARED TRAITS, indicated by the green and orange circles. 1. Which two organisms are most closely related? 2. The green dot indicates a trait that is shared by every animal on the diagram. Suggest a trait that would apply. 3. Animals A & B share a trait that animal C does not have, indicated by the orange circle. Suggest a trait that would apply.

- Construct a cladogram that provides one hypothesis about the evolutionary history for these 6 taxa. Be sure to map each of the character states for every taxon represented in the character matrix. See tips below to help get you started. You can insert a photo of a hand drawn cladogram or create one on your device. Keep in mind that cladograms are hypotheses, there are many different cladograms that can be constructed. a) Which characteristics were identified as homoplasies on your cladogram? b) Now that your tree has been constructed, how confident do you feel in your hypothesis and why?arrow_forwardGiven a cladogram for a group of species, what additional interpretation is needed to obtain a phylogenetic tree?arrow_forwardConstruct a cladogram that provides one hypothesis about the evolutionary history for these 6 taxa.
