Describe 2 homologies (structures that were shared from a common ancestor) between the Zeuglodon and the Orca.

Homologous structures can be described structures which originate in different organisms from a common ancestor and may or may not have the same functions.

Zeuglodons can be described as ancient whales and Orca is a common whale today known as the killer whale.

Scientific studies show that Zeuglodans and Orca have many structures in common such as:
