Evolutionary Relationships

Amar is making a cladogram. Out of all the species he is using, he knows that species X and Y are the least primitive and are the most closely related. Where will these organisms most likely be placed on the diagram?

• at two points close together toward the upper right of the diagram

• at two points close together toward the lower left of the diagram

• at two points far apart toward the middle of the diagram

• at two points far apart toward the upper right of the diagram
