Based on the characteristics typically associated with dorudons, blue whales, and killer whales in the context of whale evolution, the commonality they share that might not be found in other species is likely "Living in seawater."

Whales are fully adapted to marine environments, and while some other species may share some physical traits, the ability to live and thrive in seawater is a defining trait of these cetaceans.
