The ancestors of the simian immunodeficiency viruses (SIVs) that jumped from chimpanzees and monkeys, and ignited the HIV/AIDS pandemic in humans, have been dated to just a few centuries ago. These ages are substantially younger than previous estimates, according to a new study from The University of Arizona in Tucson, published May 1st in the open-access journal PLoS Computational Biology. SIV has crossed over from chimpanzees and sooty mangabeys to humans at least eleven times, giving rise...

A prohibited primate trade for the purpose of laboratory tests is flourishing in Indonesia even though local and international regulations were created to halt it, a British animal welfare group announced. The British Union for the Abolition of Vivisection (BUAV) insists that Indonesia be suspended from the Convention on the International Trade in Endangered Species (CITES) for permitting the "disturbing trade." BUAV stated that Jakarta is "breaching its own wildlife legislation as well as...

A U.S. environmental organization said it has discovered a new and significant population of the rarest primates on Earth -- Bornean orangutans. A Nature Conservancy field team said although the exact number of orangutans found in a nearly inaccessible part of Borneo is still undetermined, it is believed a medium density of the primates exists in the 2-million-acre forested area in the Sangkulirant mountains. This is some welcome news on a generally gloomy conservation agenda, the...

A university researcher has been investigating the extent of the intelligence gap between humans and some animals, saying the disparity may not be as great as we think, the Associated Press reported. Edward A. Wasserman of the University of Iowa said Thursday at the annual meeting of the American Association for the Advancement of Science that his latest study of animal mental ability suggests humans may not be the only animals that plan for the future. "I suggest we humans should keep our...

With most mammals, the biggest and most aggressive male claims the alpha male role and gets his choice of food and females. But a new study from the University of Minnesota suggests that at least among chimpanzees, smaller, more mild-mannered males can also use political behavior to secure the top position.The finding was gleaned from 10 years of observing dominant male chimpanzees in Gombe National Park, Tanzania, looking at behaviors they used to compete for alpha male status relative to...

Chimpanzees are famous for their aptitude in mimicking human behavior. Now scientists have announced that baby chimps' mental development may be more advanced than human infants. At only nine months old, the animals are as inquisitive and accomplished at recognizing parent figures as the average baby. The scientists who headed the project believe that their findings create important evidence that chimpanzees, like humans, flourish with social interaction. The more one on one their contact...

For 30 years, scientists have been studying stone-handling behavior in several troops of Japanese macaques to catch a unique glimpse of primate culture. By watching these monkeys acquire and maintain behavioral traditions from generation to generation, the scientists have gained insight into the cultural evolution of humans. Primatologists Michael A. Huffman, Charmalie A.D. Nahallage, and Jean-Baptiste Leca from the Primate Research Institute in Kyoto, Japan assessed social learning exhibited...

Scientists have discovered that orangutans can help each other get food by trading tokens, but only if the help is mutual.It seems orangutans can learn the value of tokens and trade them, helping each other win bananas, according to researchers from the University of St Andrews.This is the first documented evidence of "calculated reciprocity" in non-human primates. Gorillas and chimpanzees were much less willing to co-operate, researchers said.In particular, two orangutans - Bim and Dok - who...

The Sunda slow loris (Nycticebus coucang), also known as the greater slow loris, is a primate that can be found in Singapore, western areas of Malaysia, southern areas of Thailand, and Indonesia. This species prefers to reside in tropical rainforests but can be found in other habitats. It was first discovered in 1770 by Dutchman Arnout Vosmaer, who described it as a sloth, and was later classified with all other known lorises as a single species. Today, the Sunda slow loris is one of nine...

Gray langurs, also known as Hanuman langurs, are members of the Semnopithecus genus, which contains seven species of Old World monkeys. Members of this genus can be found in a large range on the Indian subcontinent, preferring to reside in forested areas or semi-wooded areas at low or moderate elevations, although some species can be found as high as 13,000 feet above sea level. Until 2001, Semnopithecus entellus was the only species classified within this genus. When it was separated into...

The Yellow-Tailed Woolly Monkey (Oreonax flavicauda) is a New World monkey that is native to Peru. It is a rare primate species that is found only in the Peruvian Andes, in the departments of Amaxonas and San Martin, along with the bordering areas of La Libertad, Huanuco, and Loreto. This woolly monkey was, at first, under the Lagothrix genera with other woolly monkeys, but because of debatable primary sources, they have been placed under the Oreonax genera. This genus has been suggested to...

Primatology

Primatology is the study of primates that focuses on their behaviors and possible evolution. Those who practice this science, known as primatologists, focus on primates in the wild and in laboratory settings. There are many different sub-divisions of primatology that differ based on methodology and theory, but the two major branches are Western primatology and Japanese primatology. There share basic principles, but differ culturally and in many other regards. Western primatology originated...
