Their emotional capacity has even led some researchers to draft and lobby for a cetacean-specific Declaration of Rights. Lori Marino of Emory University, Thomas I. 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. First, a caveat: "You can't really rank animals by intelligence because they're all designed to do different things," says Justin Gregg, Ph.D., a senior research associate at the Dolphin Communication Project and the author of Are Dolphins Really Smart?. Pigs are highly intelligent beings capable of recognizing themselves in a mirror, like dolphins. Like dolphins, they're capable of figuring out complex intellectual concepts that most humans can't master until kindergarten age. Animal intelligence is an oft-disputed and highly subjective topic. One measure to take into account, considering intelligence has been repeatedly linked to brain size, is the encephalization quotient or EQ which considers an animal's brain mass compared to the brain mass predicted for an animal of its size. "Dolphins have big brains, so we spent time studying them," says Gregg. 2023 American Association for the Advancement of Science. Intelligence and highly-involved social interaction became the means of survival for dolphins, and their brains adapted accordingly. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. Weve mentioned that dolphins have a larger brain than humans and they also possess greater encephalization in the cerebral cortex. Orangutans understand object necessity better than dolphins. The lacking PFC in a dolphin could help explain why theyre not as outwardly intelligent as human beings. I graduated from Rowan University in 2014 with degrees in English and Education. 6, 2013, pp. They compared dolphin encephalization quotients to those of other famously smart animals like chimpanzees, humans, gorillas and orangutans. The first scientific attempts to assess dolphin intelligence in a serious way came in the 1950s and 1960s with John Lilly, a scientist that studied bottlenose dolphin vocalization.

Lori Marino details some incredible facts about dolphins. Proceedings of the National Academy of Sciences, vol. Just like dolphins, goats have strong cognitive abilities, despite their unassuming demeanor. Much of their brain processes remain a mystery to human beings. According to several behavioral measures, Coren says dogs' mental abilities are close to a human child age 2 to 2.5 years. For human beings, the encephalization quotient is higher than any other animal at 6.56. They have the capacity to communicate through language, solve complex problems, use tools, and remember a great number of pod members for long periods of time, just like humans. "Scientific facts should transcend geographic boundaries. Aquatic Conservation: Marine and Freshwater Ecosystems, vol. ", The study mentioned such exploratory behaviors as "repetitious head circling" and "close viewing of the eye or genital region reflected in the mirror." Unlike primates, dolphins process language and auditory information in the temporal lobes, located on their brains flanks.
