Through The Stomach Is The Way To A Chimpanzee's Heart
2014-01-16 13:38:29

Max Planck Institute Chimpanzees who share their food with others have higher levels of the hormone oxytocin in their urine The ability to form long-term cooperative relationships between unrelated individuals is one of the main reasons for human’s extraordinary biological success, yet little is known about its evolution and mechanisms. The hormone oxytocin, however, plays a role in it. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany,...

Bonobos Retain Elevated Thyroid Hormones Well Into Adulthood
2013-12-18 13:23:48

Max Planck Institute Despite the fact that chimpanzees and bonobos share similar starting conditions at birth they develop different behavioral patterns later in life. These differences might be caused by different hormone levels. Researchers of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the Royal Zoological Society of Antwerp in Belgium have analyzed thyroid hormones from urine samples of zoo-living chimpanzees and bonobos. They discovered that bonobos...

Chimpanzees Are Not Conformist, Unless Peanuts Are At Play
2013-12-13 13:12:01

Lee Rannals for redOrbit.com - Your Universe Online Chimpanzees are not conformists when it comes to solving a problem, unless it involves a high pay out, according to a study published in PLOS One. Researchers from Max Planck Institute for Psycholinguistics and Evolutionary Anthropology studied how chimpanzees are rational thinkers, rather than conformists. Scientists have known that these animals are sensitive to social influences, but are capable of maintaining their own strategy in...

Human Expansion Squeezing Out Bonobo Populations In The Congo
2013-11-27 07:52:56

April Flowers for redOrbit.com - Your Universe Online The bonobo, formerly known as the pygmy chimpanzee, is quickly losing space in a world with growing human populations, according to the most detailed range-wide assessment ever conducted. The study, published in Biodiversity and Conservation, reveals that the loss of usable habitat is attributed to both forest fragmentation and poaching. The international team included researchers from University of Georgia, University of...

The Most Social Monkeys Have The Most Distinct Facial Features
2013-11-20 15:05:36

Brett Smith for redOrbit.com - Your Universe Online A new study of Old World monkeys, published in the journal Nature Communications, has suggested that they rely on facial features to recognize each other, particularly for those primates living in larger groups. The new report comes from the same UCLA biologists that released a similar analysis of the faces of nearly 130 New World monkeys from Central and South America in 2012. "Humans are crazy for Facebook, but our research...

Stem Cells Reveal Differences Humans Apes
2013-10-24 09:27:59

redOrbit Staff & Wire Reports - Your Universe Online For the first time, scientists from the Salk Institute for Biological Studies have taken stem cells from chimpanzees and bonobos and turned them into induced pluripotent stem cells (iPSCs), and their work has helped to highlight some of the differences between humans and non-human primates. This type of cell, which has the ability to form any other type of cell or tissue in the body, can be used to model diseases that would...

Long-Term Memory Helps Chimps Remember Where The Food Is
2013-10-24 05:33:05

Lee Rannals for redOrbit.com - Your Universe Online Chimpanzees rely on their long-term memory when searching for food throughout the rainforest, according to a new study published in the journal Animal Behavior. Researchers studying whether chimpanzees aim their travel to particular rainforest trees to check for fruit found that the animals use long-term memory to remember the size and location of fruit trees and feeding experiences from previous seasons. The team recorded the...

Chimps Vocalize With Purpose
2013-10-17 11:40:38

Michael Harper for redOrbit.com - Your Universe Online After analyzing the calls of chimpanzees in the wild, scientists with the University of York now believe these animals vocalize with a purpose rather than chant and howl at random. It was previously understood that the primates would simply shout when they were alarmed or felt they were in danger. However, Dr. Katie Slocombe and Dr. Anne Schel of the Department of Psychology at York recorded calls of several wild animals in Uganda and...

Human Yawn Contagious To Chimps
2013-10-17 10:47:49

[ Watch The Video: Is A Human Yawn Contagious To Chimpanzees? ] Brett Smith for redOrbit.com - Your Universe Online As fellow primates separated by only a few branches on the evolutionary tree, humans share many behaviors with chimpanzees. Now, research has shown that the older a chimp is, the more likely it is to respond to a familiar face yawning with a yawn of its own, according to a new study in the journal PLOS ONE. Referred to as 'contagious yawning,' humans – as well as dogs...

Young Bonobos Regulate Emotions Similar To Human Children
2013-10-15 08:13:32

April Flowers for redOrbit.com - Your Universe Online Striking similarities between the emotional development of bonobos and that of human children have been discovered by researchers studying young primates in an African sanctuary. The discovery, published in Proceedings of the National Academy of Sciences (PNAS), suggests that these great apes regulate their emotions in a human-like way. These findings are important to the study of human evolutionary history because it reveals that...

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...
