Great ape gestures have intentional meaning and are made with the expectation of specific behavioral responses, according to Erica Cartmill and Richard Byrne from the University of St. Andrews in the UK. The study of meaning in animal communication takes a significant step forward with the authors' new systematic approach to assessing intentional meaning in the gestural communication of non-humans, applied here to a group of orangutan gestures. Their work is published in Springer's journal...

Study suggests nonhuman animals also have metacognitive abilities - they know about what they have seen Great apes "“ orangutans, chimpanzees, bonobos and gorillas "“ realize that they can be wrong when making choices, according to Dr. Josep Call from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. Dr. Call's study was just published online in Springer's journal, Animal Cognition. In a series of three experiments, seven gorillas, eight chimpanzees, four...

Research into the long calls of male Orangutans in Borneo has given scientists new insight into how these solitary apes communicate through dense jungle. An acoustic analysis of the calls, published today in Ethology, reveals that the calls not only serve to attract females, but also contain information on the identity and the context of the caller. The international team of researchers, led by Prof. Dr. Carel van Schaik from the University of Zurich, followed three sexually active male...

The timing of molar emergence and its relation to growth and reproduction in apes was reported by two scientists at Arizona State University's Institute of Human Origins in the Dec. 28 online early edition of the Proceedings of the National Academy of Sciences (PNAS). From the smallest South American monkeys to the largest African apes, the timing of molar development and eruption is closely attuned to many fundamental aspects of a primate's biology, according to Gary Schwartz, a researcher...

Conservationists have warned that the world has less than 20 years left to save the orangutan, AFP reported. Experts say the charismatic red ape will become extinct if no action is taken to protect its jungle habitat, as deforestation and the expansion of palm oil plantations have taken a heavy toll in Malaysia and Indonesia, where there are thought to be 50-60,000 orangutans still living in the wild. Tsubouchi Toshinori from the Borneo Conservation Trust said the orangutans' habitat is...

The teeth of some apes are formed primarily to handle the most stressful times when food is scarce, according to new research performed at the National Institute of Standards and Technology (NIST). The findings imply that if humanity is serious about protecting its close evolutionary cousins, the food apes eat during these tough periods"”and where they find it"”must be included in conservation efforts. The interdisciplinary team, which brought together anthropologists from George...

Veterinarians have been tracking three orangutans they implanted with tiny transmitters as part of efforts to protect the endangered primates once they reintroduce them to the wild, a Malaysian official said Monday. French and Austrian veterinarians worked with the Wildlife Department in eastern Sabah state on Borneo island to implant specially designed coin-sized transmitters in the necks of the orangutans for the first time ever in September, said Senthilvel Nathan, the department's chief...

Wildlife conservationists say a boom in palm oil -- used extensively for biofuel and processed food like margarine -- has affected the jungles in Borneo, endangering the already declining orangutan populations, AFP reported. Experts believe that among the 50,000 to 60,000 orangutans left in the wild, some 80 percent of them are in Indonesia and the rest in Malaysia's Borneo states of Sabah and Sarawak. However, the charismatic red-haired apes will be virtually eliminated in the wild within...

A new study shows that wild orangutans in Borneo hold leaves to their mouths to make their voices sound deeper than they actually are. According to the scientists that observed the apes, the animals employ the leaf trick when predators threaten them. Holding leaves to their mouths enables the orangutans to lower the frequency of the sound they make. This strategy makes the apes appear to be a bigger target than they are to the predator. The apes make the sounds in response to approaching...

Humans evolved from orangutans, not chimpanzees, a University of Pittsburgh anthropologist says, creating a furor in the chimp camp. Fossil evidence shows striking anatomical similarities between humans and orangs, including enamel molars, similar hairlines and shoulder blades, and even the ability to smile with lips closed, Jeffrey H. Schwartz and John Grehan, director of science at the Buffalo Museum, say in the Journal of Biogeography. Even our skulls and eyebrow bone structure more...

The Sumatran Tiger (Panthera tigris sumatrae) is found only on the Indonesian island of Sumatra. The wild population is estimated at between 400 and 500 animals, occurring predominantly in the island's national parks. Recent genetic testing has revealed the presence of unique genetic markers. They indicate that it may develop into a separate species, if it is not made extinct. This has led to suggestions that the Sumatran Tiger should have greater priority for conservation than any other...

The Sumatran orangutan (Pongo abelii) is the least common of the two species of orangutans. It lives on the Sumatra island of Indonesia. They are smaller than the Bornean orangutan. Baby Sumatran orangutans are often poached as highly prized Zoo Inhabitants. The poachers often kill the baby's mother for no apparent reason. The Sumatran Orangutan is only found north of Lake Toba.

The Bornean orangutan, Pongo pygmaeus is a species of orangutan native to the island of Borneo. It is slightly larger than the other species of orangutan, the Sumatran orangutan. The Bornean orangutan is more common than the Sumatran, with about 45,000 individuals existing in the wild. There are only about 7,500 of the Sumatran species left in the wild. Orangutans are becoming increasingly endangered due to habitat destruction. Many orangutans are killed so that their babies can be captured...
