What people are saying
Discussions reference foundational research such as Jerison's 1973 work and recent studies like Marhounová et al. 2019, with some users expressing curiosity about topics like cephalopod brain evolution and the reasons behind large brain sizes, while others question terminology and suggest additional sources, reflecting moderate engagement driven by curiosity but limited deep analysis.
The discussions show a mix of agreement and ambivalence, with some referencing classic works and recent studies, but no strong consensus emerges.
The posts indicate moderate interest, especially with references to intriguing topics like cephalopods and the evolutionary reasons for large brains.
There is some engagement, as users discuss specific research findings, question terminology like DOI, and connect ideas about brain size and intelligence.
The talks suggest that the publication spurs curiosity and discussion about brain evolution and intelligence, though it does not seem to spark revolutionary ideas or debates.
Abstract in brief
- The evolution of intelligence has independently occurred in various vertebrate groups like primates, elephants, and cetaceans, with humans having more complex brains, especially in the cortex and prefrontal regions.
- Key brain features linked to intelligence include the number of cortical neurons and conduction velocity, which influence information processing, with humans having slightly more cortical neurons than other mammals.
- The high intelligence of humans likely arises from combining and enhancing traits seen in nonhuman primates, such as theory of mind, imitation, and language, rather than from entirely unique brain features.]

Evolution of the brain and intelligence https://t.co/rV4hGyobHL Most of what the brain does is run the body. The Encephalization quotient (EQ) is a measure of the ratio between observed to predicted brain mass for an animal (given size); large EQs may predict intelligence. https://t.co/2LzV4N6Y0m
