Deep Thinkers: Inside the Minds of Whales, Dolphins, and Porpoises - Janet Mann - Bog

We know whales, dolphins, and porpoises are the smartest creatures in the ocean, we read of their tool use, their self-recognition, their complex songs, and their intricate societies--but how do we know what we know? Deep Thinkers brings together the top researchers in the field to examine cetacean brains; compare the intelligence markers of cetaceans with those of birds, bats, and primates; and ask how we define intelligence in non-humans. A comprehensive exploration, setting the benchmark for future titles.
