Cetaceans are a group of mammals consisting of whales, dolphins, and porpoises. They are known for their social behavior and high intelligence. The largest species is the blue whale, which can reach almost 100 feet in length and weigh 200 tons. Despite being marine animals, Cetaceans have lungs and breathe air. DNA studies have shown that Cetaceans are closely related to even-toed ungulates, with their closest living relatives being hippos. Cetaceans' and hippo's common ancestor lived about 54 million years ago. Which homology provides evidence that Cetaceans and hippos arose from a common ancestor?

• The presence of gills

• The inability to produce milk

• The ability to lay eggs

• The presence of a backbone

• The elephant bird and the ostrich are from the same habitat in Madagascar.

• The elephant bird and the ostrich have similar diets.

• The elephant bird and the ostrich share a common ancestor.

• The elephant bird interbred with the ostrich.
