People don't always do as their neighbors do, and the same is true of neighboring chimpanzees. That's according to a report published online on May 10 in the Cell Press journal Current Biology featuring observations of wild chimps as they used hammers to crack nuts. "In humans, cultural differences are an essential part of what distinguishes neighboring groups that live in very similar environments," said Lydia Luncz of the Max Planck Institute for Evolutionary Anthropology in Leipzig,...

Meat-rich Diet Lead To Earlier Weaning, Helping Speed The Spread Of Humans
2012-04-19 11:35:43

Diets rich in meat helped early mother´s wean their babies at an earlier age and allowed them to have more children, behaviors that may have helped humans spread more quickly across the world and had a profound effect on human evolution, according to new research. Researchers from Lund University in Sweden, publishing their work in the open-access journal PLoS ONE, found a clear connection between eating meat and weaning at an earlier age. They discovered that all mammalian species...

Chimpanzee Ground Nests Offer New Insight Into Our Ancestors Descent From The Trees
2012-04-16 09:15:27

Chimpanzee behavior suggests tree-to-ground transition occurred before emergence of ancient humans The first study into rarely documented ground-nest building by wild chimpanzees offers new clues about the ancient transition of early hominins from sleeping in trees to sleeping on the ground. While most apes build nests in trees, this study, published in the American Journal of Physical Anthropology, focused on a group of wild West African chimpanzees that often shows ground-nesting...

In humans and chimpanzees knowledge is transmitted within a group by means of a majority principle The transmission of knowledge to the next generation is a key feature of human evolution. In particular, humans tend to copy behavior that is demonstrated by many other individuals. Chimpanzees and orangutans, two of our closest living relatives, also socially pass on traditional behavior and culture from one generation to another. Whether and how this process resembles the human one is still...

A study published online on April 12 in the Cell Press journal Current Biology offers some news for parents: even toddlers have a tendency to follow the crowd. That sensitivity isn't unique to humans either; chimpanzees also appear more likely to pick up habits if "everyone else is doing it." That conclusion comes from evidence that 2-year-olds and chimpanzees are more likely to copy actions when they see them repeated by three of their peers than if they see the same action done by one...

Study explores how men's mental faculties continue to respond to their physical strength and fighting ability Fighting ability, largely determined by upper body strength, continues to rule the minds of modern men, according to a new study´ by Aaron Sell from Griffith University in Australia and colleagues. Their work explores the concept that human males are designed for fighting, and shows how this fighting ability drives both their behavior and attitudes to a range issues, including...

The George Washington University's Brian Richmond and team of researchers say chimps use 2 legs to reach and carry scarce resources Most of us walk and carry items in our hands every day. These are seemingly simple activities that the majority of us don't question. But an international team of researchers, including Brian Richmond at the George Washington University, have discovered that human bipedalism, or walking upright, may have originated millions of years ago as an adaptation to...

Chimpanzees Have Policemen, Too

Conflicts are inevitable wherever there is cohabitation. This is no different with our closest relatives, the chimpanzees. Sound conflict management is crucial for group cohesion. Individuals in chimpanzee communities also ensure that there is peace and order in their group. This form of conflict management is called "policing" — the impartial intervention of a third party in a conflict. Until now, this morally motivated behavior in chimpanzees was only ever documented anecdotally....

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...
