Wide-eyed rare tarsiers found in southeast Asia, shining a spotlight on the region's conservation issues.
New footage shows a mother chimpanzee caring for her dead son in a very human way.
Over half of the non-human primate species are facing extinction in the next 50 years, and humans are to blame.
Unlike other species close to our lineage, humans have no penis bones, and this could be because of the difference between our mating practices.
Polygyny is a form of polygamy in which a single male species lives and mates with multiple females, whereas the females in question only mate with a single male. Recent anthropological studies showed that the ancient species Australopithecus afarensis (A. afarensis), in which our ancestor "Lucy" belongs to, observes polygyny.
Scientists have discovered that chimpanzees have an interesting ability to recognize not only faces but also each other's butts. The talents and abilities of many primate species have been measured by how well they are able to perform human skills. However, this new finding is a skill that not many humans can and will do. Though face recognition has been recorded, tested, and studied in animals for a very long time, this is one of the first major breakthroughs about it.
Rapid evolution of saliva in humans and primates helps defend against bacteria -- instead of developing a new system, one of our current systems adapted quickly to fill the need.
A new study revealed that when given the choice between cooperation and competition, chimpanzees opted for the former five times more frequently.
Looks like we have found the explanation as to why humans are very fond of alcohol.
For the first time, scientists document monkey feeding on bats. Experts say this could provide clues on how zoonotic pathogens spread to other animal groups, including humans.
Fossils of Lemur-like extinct primates found in China shed some light in the diversification process of primate evolution in Asia and Africa.
Human beings are not only the casualties of war in the long drawn-out civil war in Congo. The unrest has also adversely impacted the population of the world's largest ape, the Grauer's gorilla, pushing them to the brink of distinction.
Aggression is fairly common among primates, but a lethal attack among Bornean female orangutans was documented for the first time in a recent study.
There is more to determining an animal's intelligence than brain size. A new study from the University of Toronto found an ancient rodent species had a large brain that was even heftier than those of some primitive primates of the same era, but it wasn't necessarily "smarter."
