But let’s forget about humans—other animals have their own animal culture. This is the highest number of glial cells in neocortex seen in any mammal studied to date. Their brain size leads me to think so. Is a walnut nuttier than a pecan? I note this question has been already answered by some who are better qualified than I to answer it, but I will put my own spin on this question. I love our curious nature. In the book The Dynamic Human, it is argued by a group of researchers from the University of Adelaide that humans aren’t the brightest crayons in the box. What's the current state of LaTeX3 (2020)? Our sonars could hear submarines many miles away. Lori Marino, a neurobiologist who helped co-write “The Declaration of Rights for Cetaceans,” finds the limbic system of whales to be the most intriguing part of their brains, as they may be more complex than our own. We're now wondering, essentially, what goes on in a whale's head -- and why, if it's supposedly so smart, it doesn't have great works to show for it. What the new tier system means for getaways. Over time their adaptations have allowed them to live in a world with hardly any shelter where sound is more important than sight. The equivalent of this in humans would be the ability to create instantaneous holographic pictures to convey images to other people.”. While primates are often used in studies on animal intelligence because of their similarities to humans, cetaceans are frequently used as research subjects as well. No one has measured it, but it's vastly larger than a newspaper. There's really no answer to your question, unless you can define "smart.". At a meeting of the American Association for the Advancement of Science (AAAS) in February, scientists concluded that new data on cognition and culture among whales should be the guideline for international wildlife policy. From the neuroanatomical evidence she concludes that the large whale brain supports a complex intelligence that is driven by the socially complex and highly communicative lifestyle of these predators. As far as an asteroid hitting earth, you think humans can stop that from happening then you are dumber than a box of hammers. Not fascinating enough? What they find is helping separate fact from fiction. Many parts of the human brain is found in lower order animals as shown in the image below: (taken from http://en.wikipedia.org/wiki/Brain. [I have read also that pigs are smarter than either cats or dogs. It only takes a minute to sign up. Why do the mountain people make roughly spherical houses? Whales and elephants have much larger brains than humans, but have even larger bodies to go with them. The fact is, people do not have the largest brains on the planet, either in absolute size or in proportion to body size. Knowing how dynamic cetaceans are, keeping them in glorified bathtubs and forcing them to do tricks for food is insulting and cruel. R. Douglas Fields, who researches glia in his day job, frequently writes on neuroscience for Scientific American and Scientific American Mind. Do smaller intelligent animals have a higher neuron density to account for their seeming intelligence? But in proportion to body size, humans have a bigger brain followed closely by dolphins; strangely enough, whales have a smaller brain than most seals. Basically all land mammals have the basic senses more or less, so just being big does not imply more sensory input. Humans are widely considered the most highly evolved species. "We now know from field studies that a lot of the large whales exhibit some of the most complex behaviour in the animal kingdom," said Lori Marino, a neurobiologist at Emory University in Atlanta, Georgia. plus the answers in the linked question by @Bez do not support your claims. Intelligence resides in the neocortex (the thin, convuluted "rind" of the brain) rather than in other, underlying areas devoted to controlling vital housekeeping functions for the body, so Eriksen and Pakkenberg focused their investigation there. In addition to big brains and cortices, humans share more with sea mammals than you might think. Eriksen and Pakkenberg found that there were 98.2 billion non-neuronal cells, called glia, in the Minke whale neocortex. We’re Finalists for a Science Journalism Award! However, the layered structure of the whale neocortex is known to be simpler than that of humans and most other mammals. But consider the whale, whose closest living ancestor is the hippopotamus. Well did you know that, with several sound producing organs, cetaceans are capable of conveying and receiving “20 times the amount of information as we can with our hearing”? Call me Ishmael for making conjectures unflattering to humankind, but could Moby Dick have been smarter than captain Ahab? Forecasting Prices vs Returns by Deep Learning. Yet the biological facts don't quite square with Homo sapiens' arrogance. Very interesting subject, and it is clearly explained, thanks. Because of this, we might assume that having a bigger cortex is the fundamental key to intelligence. Incidentally, I worked with underwater sonar in the Navy and later worked on a research project studying the underwater vocalizations of bowhead whales in the Arctic Ocean. Co-authoring a paper with a persona non grata. It is far past time that we started to use our intelligence for good to help the plight of cetaceans. I agree Rob Lecky. Porpoises and elephants, fellow mammals known for their extraordinary mental abilities, also have bigger brains than we humans. So next time you see a brain or a skull in the Grant Museum of Zoology or any other museum, think about how that brain has evolved to adapt to its particular environment. Gulp. Second, relative size is more important than absolute size.
