Are Whales Smarter Than We Are?

R. Douglas Fields: “We humans pride ourselves on our big brains. We never seem to tire of bragging about how our supreme intelligence empowers us to lord over all other animals on the planet. Yet the biological facts don’t quite square with Homo sapiens’ arrogance. The fact is, people do not have the largest brains on the planet, either in absolute size or in proportion to body size. Whales, not people, have the biggest brains of any animal on earth.

Just how smart are whales? Why do they have such big brains? Bigger is not always better; maybe the inflated whale brain is not very sophisticated on a cellular level. We’re closer to answering such questions now, for a couple of recent papers address them squarely. What they find is helping separate fact from fiction.” (SciAm Mind Matters)
