The opossum and kangaroo both incubate their young in a pouch. This is evidence that they:

• are descended from a common ancestor that also had a pouch

• have very similar skeletal structures

• belong to the same species

• must range great distances to eat

The pelvis of a whale is no longer used making it a vestigial structure. What does it suggest about whales?

• It was like humans that also have a pelvis

• It had legs and walked on land

• It had a pelvis for the tail to help them swim

• There is no real connection between modern whales and the pelvis
