Matsuzawa, whose research focuses on chimpanzee intelligence, suggests the tradeoff hypothesis as a possible explanation as to why chimpanzees have better memory than humans for immediately capturing and retaining visual stimuli in his paper "Symbolic representation of number in chimpanzees". [1]
Chimps fall short on the cognitive scale but feel the identical emotions we do and share most of our DNA. These amazing animals deserve full constitutional protections under U.S. law.

[2] [5] Early studies focused almost entirely on studying if chimpanzees could understand the knowledge of humans. This approach turned out not to be ...
Group of chimpanzees. In primatology, the Machiavellian intelligence or social brain hypothesis describes the capacity of primates to manuever in complex social groups.

Scientist and chimpanzee expert Jane Goodall documented that humanity's. Mark Twain couldn't have been further from the truth when he wrote in an essay, "Man is the only animal that deals in that ...
Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [41] Chimpanzee hand (left) compared to human hand. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots.
