Complete your analysis here:

Which species (I, J, or K) is the closest relative to Species H? What is your evidence?
CFS:
student describes the relationship between anatomical similarities and differences in animal species
student describes the chronological difference between animal species with a common ancestor based on body structures

CFS:

Launch the Evolutionary History Modeling Tool activity: Evolution.
Goal: Use shared structures to show which species are more closely related.
Do:
Place Species C, D, and E onto the tree based on shared structures.
Press the NEW STRUCTURE boxes to indicate which new structure appeared on the two main tree branches.
Press INDICATE ORGANISM TYPE and select an option for each species.
Annotate your model to show which two species (from Species C, D, and E) are more closely related.
Tip:
It is OK to have multiple ideas about the organism type for a species.

Model here:

From species C, E, and D, which pair of species is most closely related? Explain how you know.
