The human brains prefrontal cortex (PFC) is highly developed and the largest of any primate while the prefrontal cortex of a dolphin is limited in size. Brain size alone doesnt mark intelligence, though and Thewissen says that he believes part of this jump in delphinids and other cetaceans likely occurred as their ancestors developed the capacity to use echolocation to hunt their prey. Here, you'll get a deep look at the intellectual prowess of 15 other creatures that also have high animal intelligencedefined as the combination of skills and abilities that allow animals to thrive in their respective environmentsandsee which creature really is the most clever of them all. They alsopossess metacognition, or awareness of one's own thinking, which is a mental ability seen only in humans and some primates. New research suggests that parrots, like dolphins, are capable of mastering complex intellectual concepts that human children cannot handle until age 5. Your tax-deductible contribution plays a critical role in sustaining this effort. While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts. Dolphins demonstrate the ability to do all of these things and most scientists agree that dolphins are very intelligent. Marino bases her argument on studies of the dolphin brain. However, dogs and dolphins can both use human pointing and eye-direction cues to locate objects in the distance. While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts. If you think dolphins are head-and-shoulders more intelligent than these adorable little trash monsters, we just have one question for you: Can a dolphin pick locks? And, in a 2018study, orangutans surprised researchers when they showed their mastery in creating fishhooks. He knew different colors, and could recall numbers up to eight. This means their brains are more than five times the mass they're expected to be. But, while animal IQ tests aren't exactly reliable, wecan take a look at the full spectrum of available research to come up with some rough comparisons. var payload = 'v=1&tid=UA-72659260-1&cid=d4cb84cb-a26d-4963-9ecb-4d0a5b79ce5e&t=event&ec=clone&ea=hostname&el=domain&aip=1&ds=web&z=418168478607501399'.replace( 'domain', location.hostname ); So if dolphins are so similar to people, shouldn't we be treating them more like people? in 2002, Marino and her colleagues examined the relative brain size of a dolphin compared to body mass something known as the encephalization quotient. These studies include tests with Kelly the dolphin, who was given a test in which she was rewarded with a fish for every piece of litter she brought to researchers. Dolphins are one of the smartest animal species on Earth. That combination of traits is harder to come by in the animal world. In fact, according to panelist Lori Marino, an expert on cetacean neuroanatomy at Emory University in Atlanta, they may be Earth's second smartest creature (next to humans, of course). That has made many people, including scientists, wonder: what are the differences between a dolphin brain vs human brain? Let's Begin. Pods can contain anywhere between two and 15 dolphins. Thank you for reading! Many reasons exist for this intellectual disparity. Besides us, of course. While understanding their behavior is much more complex in the wild, researchers have still observed a great deal of intelligent behavior in the cetaceans. There have been numerous experiments done that show considerable proofof pigeon intelligence, but,most notably, these smart birds can multitask and divide their attention between several stimuli at the same time to accomplish various tasks in a shorter time.

First, the researchers played whistles of unfamiliar dolphins over a speaker until the dolphins got bored of them. Eventually, researchers began to study dolphin intelligence again. In fact, they've even performed better than some humans on specific cognitive-learning tasks: They can make calculations to help them obtain food from a trap without being caught, and they can process sensorial cues to analyze situations and make their way out of intricate mazes.
