Evolutionary divergence of humans from chimpanzees likely occurred some 8 million years ago rather than the 5 million year estimate widely accepted by scientists, a new statistical model suggests. The revised estimate of when the human species parted ways from its closest primate relatives should enable scientists to better interpret the history of human evolution, said Robert D. Martin, curator of biological anthropology at the Field Museum, and a co-author of the new study appearing in the...

According to this paper, what is exceptional about these new...

Typically, monkeys don't know what to make of a mirror. They may ignore it or interpret their reflection as another, invading monkey, but they don't recognize the reflection as their own image. Chimpanzees and people pass this "mark" test "” they obviously recognize their own reflection and make funny faces, look at a temporary mark that the scientists have placed on their face or wonder how they got so old and grey. For 40 years, scientists have concluded from this type of behavior...

A new endangered species of ape was discovered in the tropical rainforests of Asia by its unique song, German scientists said Tuesday. The new species of crested gibbon, considered one of the most endangered primate species in the world, is found around the rainforests of Vietnam, Laos and Cambodia. It is called the Northern Buffed-cheeked Gibbon, Nomascus annamensis, a statement by the German Primate Center (DPZ) said. Christian Roos, from the DPZ, said the discovery was a "minor...

European Union on Wednesday ruled to ban animal testing on primates -- including chimpanzees, gorillas, bonobos and orangutans -- as it tries to scale back the number of animals used in scientific research. After two years of intense debate on how to protect animal welfare without hindering scientific research, the European Parliament agreed to cut back the number of animal tests in Europe and enforce stricter regulations for animal use in research. Under the new legislation, experiments on...

An international collaboration led by a University of Pennsylvania anthropologist has shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys as the circadian rhythm that regulates periods of sleep and wakefulness. The study also indicates that when the senses relay information on these environmental factors, it can influence daily activity and, in the case of a particular monkey species, may have even produced...

Loss of habitat may lead to increased primate-human conflict suggests research Scientists from Kyoto University, Japan, studying chimpanzees in Guinea have published research revealing why primates attack humans and what prevention measures can be taken. The study, published in a special issue of The American Journal of Primatology, suggests that while rare, attacks by primates on humans may increase as wild habitat is increasingly converted for agriculture. The team was based in the village...

Pass the chips and hand over the remote. In a study involving the first-ever daily energy expenditure measurements in apes, a researcher from Washington University in St. Louis and his team have determined that orangutans living in a large indoor/outdoor habitat used less energy, relative to body mass, than nearly any eutherian mammal ever measured, including sedentary humans. All this despite activity levels similar to orangutans in the wild. "It's like finding a sloth in your family tree,"...

Brown Spider Monkey, Ateles hybridus
2014-04-28 09:58:59

Brown Spider Monkeys have long and thin limbs with their forelimbs being longer than their hind limbs. They also have a distinctive 75 centimeter long flexible and thin prehensile tail which at times acts like a fifth limb. The tip is hairless with ridged skin for better grip. All of these features of their body make it possible for them to climb trees and high elevations, hang and swing from one tree to another without having to lower themselves to the ground frequently. Their hands are...

The Northern Muriqui (Brachyteles hypoxanthus) is an endangered muriqui, meaning woolly spider monkey, species that is endemic to Brazil. It is rare among primates in that it shows egaliterian social relationships. It can be found in the Atlantic forest region of the Brazilian states of Espirito Santo, Minas Gerais, Bahia, and Rio de Janeiro. Muriquis are the biggest species of New World monkeys. The northern muriqui can grow up to 4.3 feet tall. This species feeds mostly on leaves and twigs,...

Sunda Slow Loris, Nycticebus coucang
2014-04-16 11:22:42

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

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...

Yellow-Tailed Woolly Monkey, Oreonax flavicauda
2014-04-10 14:40:56

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...
