Diana monkeys have been observed to respond to the most likely reason for the call, typically a human or leopard, based on the situation and respond according to that. If they deem a leopard is the more likely predator in the vicinity they will produce their own leopard-specific alarm call but if they think it is a human, they will remain ...
The authors conclude, "this study found evidence that humans can perform better than suggested by Matsuzawa in the limited-hold memory task. However, human performance is still below that of chimpanzees. This difference appears to stem from an inability to keep the location of symbols in working memory" [5]
Illustration from Apes and Monkeys: Their Life and Language (1900) Richard Lynch Garner was the first researcher to explore in depth the communication skills of nonhuman primates. He began in 1884 studying monkeys in American zoos and later travelled to Africa to study gorillas and chimpanzees. [6]
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 ...
A monkey drinking Frooti from a juice box using its hands. The mind and behavior of non-human animals has captivated the human imagination for centuries. Many writers, such as Descartes, have speculated about the presence or absence of the animal mind. [7]
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [72] - although humans may have four or five. [78] The main hominid molar cusp ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.

[b] The term has a history of rather imprecise usage—and of comedic or punning usage in the vernacular.Its earliest meaning was generally of any non-human anthropoid primate, as is still the case for its cognates in other Germanic languages.
Although the evidence base for our understanding of the neural basis of human intelligence has increased greatly over the past 30 years, even more research is needed to fully understand it. [ 1 ] The neural basis of intelligence has also been examined in animals such as primates , cetaceans , and rodents .
