The evolution of human intelligence is closely tied to the evolution of the human brain and to the origin of language.The timeline of human evolution spans approximately seven million years, [1] from the separation of the genus Pan until the emergence of behavioral modernity by 50,000 years ago.
The Dragons of Eden: Speculations on the Evolution of Human Intelligence is a 1977 book by Carl Sagan, in which the author combines the fields of anthropology, evolutionary biology, psychology, and computer science to give a perspective on how human intelligence may have evolved.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason.
The history of human thought covers the history of philosophy, history of science and history of political thought and spans across the history of humanity. The academic discipline studying it is called intellectual history .
Genetic data can provide important insight into human evolution. In May 2023, scientists reported a more complicated pathway of human evolution than previously understood. According to the studies, humans evolved from different places and times in Africa, instead of from a single location and period of time. [276] [277]
The cognitive tradeoff hypothesis argues that in the cognitive evolution of humans, there was an evolutionary tradeoff between short-term working memory and complex language skills. Specifically, early hominids sacrificed the robust working memory seen in chimpanzees for more complex representations and hierarchical organization used in language.
This is evidenced by Perrault's pluckiest heroines, the women at the center of "Ricky of the Tuft," a story that prizes intelligence over physical attraction among potential female partners. The story, unsurprisingly, was not included in the Grimms' anthology; it'd have been . a strange, lovely anomaly among the rest.
Neuroscience and intelligence refers to the various neurological factors that are partly responsible for the variation of intelligence within species or between different species. A large amount of research in this area has been focused on the neural basis of human intelligence.
