Tooth development and weaning in chimpanzees not as closely related as once thought, researchers say For more than two decades, scientists have relied on studies that linked juvenile primate tooth development with their weaning as a rough proxy for understanding similar developmental landmarks in the evolution of early humans. New research from Harvard, however, is challenging those conclusions by showing that tooth development and weaning aren't as closely related as previously thought....

Monogamous Owl Monkeys Reproduce More Than Those With Multiple Partners
2013-01-25 11:12:27

University of Pennsylvania Breaking up is hard to do – and can be detrimental to one´s reproductive fitness, according to a new University of Pennsylvania study. Focusing on wide-eyed, nocturnal owl monkeys, considered a socially monogamous species, the research reveals that, when an owl monkey pair is severed by an intruding individual, the mate who takes up with a new partner produces fewer offspring than a monkey who sticks with its tried-and-true partner. The findings...

[Watch Video: Smithsonian Orangutans Using iPads for Enrichment] Michael Harper for redOrbit.com — Your Universe Online The Smithsonian National Zoological Park in Washington, DC has recently begun using Apple iPads to interact with a zoo favorite, orangutans.  The Smithsonian now joins 12 other zoos around the world who use this high tech program appropriately called “Apps for Apes.” According to Smithsonian officials, this program is great for enriching the...

Mexican Howler Monkeys Stressed Out From Longer Foraging Times
2013-01-23 05:26:36

April Flowers for redOrbit.com - Your Universe Online Because of human disturbance to its habitat, the endangered Mexican howler monkey is consuming more leaves and less fruit, forcing them to invest much more time foraging for nutrition. Hormone analysis reveals that this is leading to increased stress levels in the monkeys. The findings of this study, led by the University of Cambridge, were published in a recent issue of International Journal of Primatology. The research was carried...

Human Hands Evolved For Fighting And Punching
2012-12-20 10:48:00

Lawrence LeBlond for redOrbit.com — Your Universe Online The human hand is unique in the animal kingdom. As we evolved from apes, it was one of the most distinctive features that truly distinguished us from our closest living relatives. But while we know our hands can allow us to do many things, such as play music, make art, and easily grasp and manipulate tools, they have actually evolved for a vastly different reason, according to new research. That research, conducted by the...

Borneo Slow Loris Family Welcomes New Members
2012-12-14 09:14:37

April Flowers for redOrbit.com - Your Universe Online While studying the elusive nocturnal primate the slow loris in the jungles of Borneo, an international team of scientists discovered an entirely new species. Detailed in the American Journal of Primatology, the team analyzed the distinctive facial fur markings to reveal the existence of this new species. Another two species that were previously considered sub-species are also being officially recognized as unique because of this study....

Paternal Voice Recognition Study Provides Hints Of Social Evolution
2012-11-30 13:18:59

Lawrence LeBlond for redOrbit.com - Your Universe Online New research from Arizona State University (ASU) and the University of Veterinary Medicine Hannover in Germany, for the first time, show paternal voice recognition in a not-so-social animal that may provide insight into early primates from which humans evolved. Studying the grey-mouse lemur, researchers discovered these small primates pay close attention to alarm regardless of where it is coming from, but they are selective when...

Seasonal Diet Changes Can Cause Reproductive Stress In Primates
2012-11-29 08:58:17

Public Library of Science Nutritional shifts caused by seasonal diets influence reproductive behavior in blue monkeys When seasonal changes affect food availability, omnivores like blue monkeys adapt by changing their diets, but such nutritional changes may impact female reproduction, according to research published November 28 in the open access journal PLOS ONE by Steffen Foerster from Barnard College, and colleagues from Columbia University and the Smithsonian Institution. The...

Estrogenic Plants Alters Hormones In Monkeys
2012-11-20 20:59:37

Lee Rannals for redOrbit.com — Your Universe Online A new study says eating certain vegetables may influence hormone levels and behaviors like aggression and sexual activity in monkeys. The research from the University of California, Berkeley is the first to observe the connection between plant-based estrogenic compounds and behavior in wild primates. They found that the more leaves of Millettia dura the male red colobus monkeys ate, the higher their levels of estradiol 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...

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...
