Whales That Walked and Orcas From Another World: The Mind-Boggling Saga of Cetaceans

Whales, those massive, graceful denizens of the ocean, hold a story that’s as mind-boggling as it is inspiring. These leviathans didn’t always swim; some of their ancestors once walked the Earth. Over the eons, they “decided” (if evolution could speak) that land wasn’t all it was cracked up to be, and so they returned to the sea. Among their kin, orcas, or killer whales, emerge as apex predators with intelligence, culture, and behavior so advanced they feel like visitors from another world.
