Humans have the same receptors for detecting odors related to sex as do other apes and primates. But each species uses them in different ways, stemming from the way the genes for these receptors have evolved over time, according to Duke University researchers. http://www.physorg.com/news179507288.html Biology Tue, 08 Dec 2009 15:40:13 EST news179507288 Malaysian wildlife authorities are using electronic implants to keep track of orangutans in a bid to protect the endangered apes after they are freed into the wild, an official said Tuesday. http://www.physorg.com/news178296802.html Biology Tue, 24 Nov 2009 15:20:01 EST news178296802 Pet owners and scientists who spend a lot of time in the wild say that they can tell when an animal is upset by the sound of its voice. Now new analyses of animal calls may offer an explanation; humans seem to express frustration in the same way as other mammals. http://www.physorg.com/news176658273.html Biology Thu, 05 Nov 2009 17:10:03 EST news176658273 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 Niņo 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. http://www.physorg.com/news175896415.html Biology Tue, 27 Oct 2009 22:00:01 EST news175896415 (PhysOrg.com) -- Spotted hyenas may not be smarter than chimpanzees, but a new study shows that they outperform the primates on cooperative problem-solving tests. http://www.physorg.com/news173356849.html Biology Mon, 28 Sep 2009 11:41:59 EST news173356849 Well-preserved craniodental fossil remains from two primate species have been discovered during excavations at an Algerian site. They reveal that the small primate Algeripithecus, which is 50 million years old and until now was considered as the most ancient African anthropoid, in fact belonged to another group, that of the crown strepsirhines. http://www.physorg.com/news172218403.html Other Sciences Tue, 15 Sep 2009 07:40:04 EST news172218403 (PhysOrg.com) -- Music is one of the surest ways to influence human emotions; most people unconsciously recognize and respond to music that is happy, sad, fearful or mellow. But psychologists who have tried to trace the evolutionary roots of these responses usually hit a dead end. Nonhuman primates scarcely respond to human music, and instead prefer silence. http://www.physorg.com/news171052183.html Biology Tue, 01 Sep 2009 19:30:36 EST news171052183 A new study has concluded that one key part of the immune system, the ability of vitamin D to regulate anti-bactericidal proteins, is so important that is has been conserved through almost 60 million years of evolution and is shared only by primates, including humans - but no other known animal species. http://www.physorg.com/news169831861.html Medicine & Health Tue, 18 Aug 2009 16:31:33 EST news169831861 When primates don`t get the same rewards as their peers, they often refuse them. A Georgia State University researcher is exploring why this reaction happens, and how reactions to inequality have evolved in related species, including humans. http://www.physorg.com/news169826073.html Biology Tue, 18 Aug 2009 14:55:02 EST news169826073 Although you wouldn't want one to balance your checkbook, dogs can count. http://www.physorg.com/news168967215.html Biology Sat, 08 Aug 2009 16:20:51 EST news168967215 When it comes to investigating mysteries, Sherlock Holmes has nothing on Rice University biologist Amy Dunham.

And, according to a new report published online on June 25th in Current Biology, a Cell Press publication, the way our brains process gaze-direction is much more sophisticated than a simple eyes-right versus eyes-left. http://www.physorg.com/news165152466.html Medicine & Health Thu, 25 Jun 2009 13:20:04 EST news165152466 (PhysOrg.com) -- Evolutionarily speaking, baboons may be our more distant cousins among primates. But when it comes to our experiences with malaria over the course of time, it seems the stories of our two species have followed very similar plots. http://www.physorg.com/news165068326.html Medicine & Health Wed, 24 Jun 2009 13:20:34 EST news165068326 Scientists at Harvard University have shown, for the first time, that intelligence varies among individual monkeys within a species - in this case, the cotton-top tamarin. http://www.physorg.com/news164422912.html Biology Wed, 17 Jun 2009 02:05:59 EST news164422912 The threat of snakes gave primates superior vision and large brains -- and fueled a critical aspect of human evolution, UC Davis anthropology professor Lynne Isbell argues in a new book. http://www.physorg.com/news160389288.html Biology Fri, 01 May 2009 09:35:46 EST news160389288 (PhysOrg.com) -- Researchers from the University of California at Davis (USA) and the Max Planck Institute for Evolutionary Anthropology in Leipzig (Germany) present a virtual reconstruction of a female Neanderthal pelvis from Tabun (Israel). Although the size of Tabun`s reconstructed birth canal shows that Neanderthal childbirth was about as difficult as in present-day humans, the shape indicates that Neanderthals retained a more primitive birth mechanism than modern humans. http://www.physorg.com/news159548688.html Other Sciences Tue, 21 Apr 2009 16:05:25 EST news159548688 Diet - and how it has shaped our genome - occupies much of an evolutionary scientist's time. Anne Stone, associate professor of anthropology in Arizona State University's School of Human Evolution and Social Change, will discuss how diet holds keys to understanding who we are, how we live and form societies, and how we evolved from hunter-gatherers to agriculturists, all the way to modern urban dwellers, at the American Association for the Advancement of Science annual meeting in her seminar - "Genetic Perspectives on the Evolution of Human Diets". http://www.physorg.com/news153675034.html Biology Thu, 12 Feb 2009 15:31:31 EST news153675034 (PhysOrg.com) -- When Tchaikovsky penned The Nutcracker, the last thing he probably had in mind was a capuchin monkey. And yet new research, co-directed by a researcher at the University of Georgia, is changing our view about which nutcracker should be the focus of our attention. http://www.physorg.com/news152984550.html Biology Wed, 04 Feb 2009 15:42:55 EST news152984550 Why have some of our genes evolved rapidly? It is widely believed that Darwinian natural selection is responsible, but research led by a group at Uppsala University, suggests that a separate neutral (nonadaptive) process has made a significant contribution to human evolution. Their results have been published today in the journal PLoS Biology. http://www.physorg.com/news152252193.html Biology Tue, 27 Jan 2009 04:16:58 EST news152252193 The genome of a squirrel-sized, saucer-eyed lemur from Madagascar may help scientists understand how HIV-like viruses coevolved with primates, according to new research from the Stanford University School of Medicine. The discovery, to be published online on Dec. 1 in the Proceedings of the National Academy of Sciences, could provide insight into why non-human primates don't get AIDS and lead to treatments for humans. http://www.physorg.com/news147374817.html Medicine & Health Mon, 01 Dec 2008 17:26:57 EST news147374817 Why are so many infectious diseases jumping from animals to humans? Why do we have so little capacity to predict epidemics, or avoid them?
