The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
The evolution of cognition is the process by which life on Earth has gone from organisms with little to no cognitive function to a greatly varying display of cognitive function that we see in organisms today. Animal cognition is largely studied by observing behavior, which makes studying extinct species
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 .
Main differences rely on the evolution of non-coding genomic regions, involved in the regulation of gene expression. This leads to differential expression of genes during the development of the human brain compared to other species, including chimpanzees. Some of these regions evolved fast in the human genome (human accelerated regions).
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
Cephalopods like the octopus or giant squid represent "an independent experiment in the evolution of large brains and complex behaviour" predicated on the same neural systems as our closer mammalian relatives. Neither language nor a worldview is needed for a measure of intelligence in these "other minds" that share planet Earth. [2]
The AP reports that about 54 million years ago mammals, humans' earliest primate ancestor included, "shriveled a bit in size at least twice in Earth's history when temperatures spiked."
The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities. First described in humans, the g factor has since been identified in a number of nonhuman species.
