Link. Recently published information regarding the increased folding of Albert Einstein's cerebral cortex compared to that of other humans supports this theory. Humans have evolved in a way that allows our brain to pack a lot more neurons into a smaller … Moreover, neither cetaceans nor any other large-brained species have been found to possess more neocortical neurons than humans. By counting the number of neurons in brains, one scientist revolutionized our view of why Homo sapiens and nonhuman primates are so much smarter than other animals. Inside of their flippers, dolphins have five phalanges, or finger bones. Opposable thumbs is typically what is cited in evolutionary psychology classes. Dolphins and elephants just plain have fewer neurons too. Along with the five phalanges, dolphins also have carpals, ulna, and radius and humerus bone fragments, just like humans. A quick google search of “dolphin flipper bones” reveals that our hands and dolphin flippers are actually far more similar than they are different. For dolphins, echolocation is the primary sense, far stronger than vision. Researchers developed sonar and radar inspired by the echolocation abilities of dolphins and bats. Dolphins are capable of “highly developed spoken language” which closely resembles human communication, scientists have suggested. The only animal to have a more folded cortex than man is the dolphin. What does it mean when dolphins have a higher ratio of neural density than humans? Humans don’t have this capability, but dolphins do, and they use it to navigate waters and find food. The more folded the cortex, the more room within the brain to hold additional brain cells with which to perform processing of information. In this study, we studied the brain from the long-finned pilot whale (Globicephala melas Traill, 1809), which has an EQ of 2.39 (Marino, 2004).
