Which is bigger a dolphin or a toothed whale?
Our Brains Are Very Similar. For her PhD thesis, scientist Lori Marino compared the skulls of dolphins and toothed whales to apes. She found that in terms of size relative to body, dolphins have larger brains. In fact, they come in second for largest brain relative to body size, right below humans.
Are whales and dolphins smarter than humans?
Whales and dolphins are smart ! Perhaps we humans need to reconsider the traditional view that we are exceptional and since no other creature can think or communicate like a human, no other species can match our intelligence? The evidence is that – in some ways – whales and dolphins have communication abilities that are superior to those of human beings.
What is the relationship between dolphins and humans?
