The second list shows the number of neurons in the structure that has been found to be representative of animal intelligence. [1] The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [2] [1]
It has been suggested that g is related to evolutionary life histories and the evolution of intelligence [131] as well as to social learning and cultural intelligence. [ 132 ] [ 133 ] Non-human models of g have been used in genetic [ 134 ] and neurological [ 135 ] research on intelligence to help understand the mechanisms behind variation in g .
Animal intelligence is the study about the origins of animal intelligence by studying the mental processes of other species. The basic premise of this research is that we need to understand the processes of association and learning in other animals in order to understand how human culture, art, religion, mathematics and more may have developed.
Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.
Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins. In 2014, a study found for first time that the long-finned pilot whale has more neocortical neurons than any other mammal, including humans ...
The visual and auditory senses are well developed in most species, though the tactile and olfactory senses are well realized only in a few groups. Birds communicate using visual signals as well as through the use of calls and song. The testing of intelligence in birds is therefore usually based on studying responses to sensory stimuli.
Pigs are among the most intelligent mammals on the planet; as such, they display a wide range of complex behaviors, like being able to play video games, understanding human instructions and even a pig species has been observed using tools.
Elephants are believed to rank equal with dolphins in terms of problem-solving abilities, [9] and many scientists tend to rank elephant intelligence at the same level as cetaceans; a 2011 article published by ABC Science suggests that, "elephants [are as] smart as chimps, [and] dolphins".
