Conflict management is crucial for social group cohesion, and while humans may still be working out some of the details, new research shows that some chimpanzees engage in impartial, third-party "policing" activity as well. The full results are published Mar. 7 in the open access journal PLoS ONE. Anthropologists from the University of Zurich, led by Prof. Carel van Schaik and Claudia Rudolf von Rohr, reveal that chimpanzees mediate conflicts between other group members not for their own...

Nearby Chimpanzee Populations Show Greater Genetic Diversity Than Distant Human Populations
2012-03-03 05:27:54

Chimpanzee populations living in relatively close proximity are substantially more different genetically than humans living on different continents, according to a study published March 2 in PLoS Genetics. The study suggests that genomics can provide a valuable new tool for use in chimpanzee conservation, with the potential to identify the population of origin of an individual chimpanzee or the provenance of a sample of bush meat. Common chimpanzees in equatorial Africa have long been...

Chimpanzee populations living in close proximity are substantially more different genetically than humans living on different continents Chimpanzee populations living in close proximity are substantially more different genetically than humans living on different continents, according to a study published in PLoS Genetics. Research conducted by scientists from the universities of Oxford and Cambridge, the Centre Pasteur du Cameroun, and the Biomedical Primate Research Centre suggests that...

Dogs are better than chimps at interpreting pointing gestures, according to a study published in the online journal PLoS ONE. Katharina Kirchhofer, of the Max Planck Institute for Evolutionary Anthropology in Germany, led a team in the investigation of 20 chimps and 32 dogs presented with the same task: retrieving an object the experimenter wanted, as indicated by the experimenter pointing. The researchers found that the dogs performed well, but the chimps failed to identify the object of...

The Consequences Of Non-intervention For Infectious Disease In African Great Apes
2012-02-07 05:00:12

Infectious disease has joined poaching and habitat loss as a major threat to the survival of African great apes as they have become restricted to ever-smaller populations. Despite the work of dedicated conservationists, efforts to save our closest living relatives from ecological extinction are largely failing, and new scientific approaches are necessary to analyze major threats and find innovative solutions. In response to this crisis, researchers at UC Santa Barbara's National Center for...

Over the first few years of life, human cognition continues to develop, soaking up information and experiences from the environment and far surpassing the abilities of even our nearest primate relatives. In a study published online today in Genome Research, researchers have identified extended synaptic development in the human brain relative to other primates, a finding that sheds new light on the biology and evolution of human cognition. "Why can we absorb environmental information during...

Bonobos‘ Unusual Success Story
2012-01-24 04:00:24

Dominant males invest in friendly relationships with females Mate competition by males over females is common in many animal species. During mating season male testosterone levels rise, resulting in an increase in aggressive behavior and masculine features. Male bonobos, however, invest much more into friendly relationships with females. Elevated testosterone and aggression levels would collide with this increased tendency towards forming pair-relationships. Bonobos are among the...

Why are the faces of primates so dramatically different from one another? UCLA biologists working as "evolutionary detectives" studied the faces of 129 adult male primates from Central and South America, and they offer some answers in research published today, Jan. 11, in the early online edition of the journal Proceedings of the Royal Society B. The faces they studied evolved over at least 24 million years, they report. "If you look at New World primates, you're immediately struck by...

Chimpanzees might be able to determine whether or not their fellow chimps need to hear a specific message, according to a new study published in the journal Current Biology. According to Guardian Science Correspondent Ian Sample, researchers from the University of St. Andrews, the Max Planck Institute for Evolutionary Anthropology, and the Budongo Conservation Field Station in Uganda, observed the creatures selectively sounding a warning call, apparently based on whether or not they...

Ugandan Red Colobus, Procolobus tephrosceles
2012-06-21 13:36:08

The Ugandan red colobus (Procolobus tephrosceles) is a primate native to Africa. It is an Old World monkey that was not classified as its own species until 2001. Its range includes five areas of Uganda and Tanzania that equal 621.3 miles. These areas include the edge of Lake Victoria in Tanzania and Kibale National Park in Uganda, where the largest population is thought to be located. The preferred habitat of this monkey depends on its location, and it some areas, sustainable habitat is...

The bonobo (Pan paniscus), until recently is usually called the pygmy chimpanzee and less often the dwarf or gracile chimpanzee. It is one of the two species of chimpanzees. Physical characteristics Its head is smaller than that of the Common Chimpanzee but has a higher forehead. It has a black face with pink lips, small ears, wide nostrils, and long hair on its head. Females have slightly prominent breasts in contrast to the flat breasts of other female apes, though not as prominent...
