Most of the linguistic functions in humans are controlled by the left cerebral hemisphere. A study of captive chimpanzees at the Yerkes National Primate Research Center (Atlanta, Georgia), reported in the January 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex), suggests that this "hemispheric lateralization" for language may have its evolutionary roots in the gestural communication of our common ancestors. A large majority of the chimpanzees in the study showed a...

Results may help to set conservation priorities for this critically endangered species The most extensive DNA study to-date of Africa's rarest monkey reveals that the species had an intriguing sexual past. Of the last two remaining populations of the recently discovered kipunji, one population shows evidence of past mating with baboons while the other does not, says a new study in Biology Letters. The results may help to set conservation priorities for this critically endangered species,...

Two Penn State University researchers have carried out one of the first-ever analyses of the effects of global warming on endangered primates. This innovative work by Graduate Student Ruscena Wiederholt and Associate Professor of Biology Eric Post examined how El Niño warming affected the abundance of four New World monkeys over decades. The research will be published on 28 October 2009 in the Royal Society journal Biology Letters, a fast-track journal of the Royal...

Music serves as a natural and non-invasive intervention for patients with severe neurological disorders to promote long-term memory, social interaction and communication. However, there is currently no plausible explanation of its neural basis for why and how music affects physical and psychosocial responses. Origins of music perception in humans may have their foundation in animal communication calls, as evidenced here in non-human primates. Many speech sounds and animal vocalizations, for...

U.S. evolutionary anthropologists say they've discovered spotted hyenas outperform primates on cooperative problem-solving tests. Duke University scientists led by Associate Professor Christine Drea said captive pairs of spotted hyenas (Crocuta crocuta) that needed to tug two ropes in unison to earn a food reward cooperated successfully and learned the maneuvers quickly with no training. And the researchers discovered experienced hyenas even helped inexperienced partners do the trick. When...

Spotted hyenas may not be smarter than chimpanzees, but a new study shows that they outperform the primates on cooperative problem-solving tests. Captive pairs of spotted hyenas (Crocuta crocuta) that needed to tug two ropes in unison to earn a food reward cooperated successfully and learned the maneuvers quickly with no training. Experienced hyenas even helped inexperienced partners do the trick. When confronted with a similar task, chimpanzees and other primates often require extensive...

Experts say endangered species are being threatened by Internet advertisements asking people adopt "playful primates" from Cameroon, AFP reported. It is illegal and forbidden to deal primates in the central African country. But one environmental activist in the front line said that over the past three years the Internet has led to a flourishing trade in endangered species. The Last Great Ape Organization (Laga-Cameroon) is a small non-governmental organization that works in conjunction with...

U.S. scientists say the ability of vitamin D to regulate anti-bactericidal proteins has been conserved in primates for nearly 60 million years of evolution. Oregon State University researchers said that part of the immune system is shared only by primates, including humans -- but no other known animal species. The fact that the vitamin-D mediated immune response has been retained through millions of years of evolutionary selection -- and is still found in species ranging from squirrel monkeys...

 A prehistoric water-filled cave in the Dominican Republic has become a "treasure trove" with the announcement by Indiana University archaeologists of the discovery of stone tools, a small primate skull in remarkable condition, and the claws, jawbone and other bones of several species of sloths.The discoveries extend by thousands of years the scope of investigations led Charles Beeker, director of Academic Diving and Underwater Science Programs at IU Bloomington's School of Health,...

To understand how climate change may affect species survival, we need to understand how climate influences their time-keeping.New research published in the journal Biological Reviews points to time as a major factor in determining whether a species is capable of surviving in a particular habitat.In their paper "ËœTime as an ecological constraint' (Biological Reviews, August 2009), Professor Robin Dunbar of the University of Oxford, Dr Amanda Korstjens of Bournemouth University, and...

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...

Northern Muriqui, Brachyteles hypoxanthus
2014-04-17 13:48:56

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
2014-04-10 16:46:11

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...
