The mirror test also called the mark test or MSR, for "mirror self recognition" test is a technique designed to measure self-awareness. She notes, for example, that in the wild, dolphins have a home range of about 100 square kilometers.

In human beings, the PFC is in charge of executive functions, allowing us to work towards specific goals and determine potential outcomes. This kind of social learning happens frequently among wild species, but most often, the techniques that permeate animal populations involve essential tasks, such as feeding and mating. However, dolphins also excel intelligence-based tests. Another jump happened again in the early delphinids, the ancestors of modern dolphins, porpoises and belugas, about 27 million years ago. Bottlenose dolphins off the coast of Western Australia have been observed using sea sponges as snout protecting tools while rooting around in the sand on the seafloor for fish.

They're known to use sticks to catch ants and termites, as a kind of rudimentary form of a fishing (or, rather, bug-catching) pole. So, why does this signify intelligence? Dolphin Research Center. These birds solve puzzles and also understand the concept of cause and effect. Many scientists hypothesize that dolphins' highly-developed paralimbic systems play a large role in the intimate and complex social and emotional bonds that exist within dolphin communities.

Bottlenose dolphins off the coast of Western Australia have been observed, as snout protecting tools while rooting around in the sand on the seafloor for fish. What's more, they follow a very humanlike trajectory of language development, starting out as babblers and learning the laws of language over time. The lacking PFC in a dolphin could help explain why theyre not as outwardly intelligent as human beings. "Bottlenose Dolphins Retain Individual Vocal Labels In Multi-Level Alliances." Aside from being easily trainable, dolphins are able to recognize themselves in mirrors, notice unfamiliar marks on their body in a reflection, recognize images on television, and have impressive memory. In fact, humans have a larger brain than dolphins relative to their body size. 6, 2010, pp. The trouble is, the questionable ethics of some of his experiments often overshadows that work and led to a drought on serious research on dolphin smarts that lasted for years, Marino says.
