Who got the colour vision first, humans or chimpanzees? According to biologists from Georgia-based Emory University, humans actually got the ability to see colours from gorillas and chimpanzees in the evolution process.
The microbes living in people's guts play a very important role in keeping us healthy, but the ones existing in our body today are a lot less diverse than the ones present within the humans' closest relatives, the African apes, says a research.
A new research has revealed that chimpanzees have innate lethal aggression, refuting the theory of chimpanzees' inter-community wars being a result of human impact, such as habitat destruction or food provisioning, rather than adaptive strategies.
Just like humans, some chimpanzees are smarter than others, and about half of that variation in intelligence depends on the genes that individuals carry and pass on from one generation to the next, says a study.
Researchers have made a breakthrough in understanding human`s ability to form long-term cooperative relationships between unrelated individuals is one of the main reasons for human`s extraordinary biological success.
