 | Using mice as models, researchers at the Max Planck Institute for Evolutionary Anthropology traced some of the differences between humans and chimpanzees to differences in our diet. ...> Full Article |
 | While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists at the University of California, Santa Cruz led by biomolecular engineering professor David Haussler has investigated this less-studied idea, carrying out the first systematic computational analysis to identify long-established genes that have been lost across millions of years of evolution leading to the human species. ...> Full Article |

 | Researchers have found evidence that supports the theory that reproductive competition during the evolution of primate species has occurred at the level of sperm cell motility. ...> Full Article |
They say that the way to a man's heart is through his stomach and the same could be said for female chimpanzees. Researchers studying wild chimps in West Africa have discovered that males pinch desirable fruits from local farms and orchards as a means of attracting female mates.

A difference of only a few percent in DNA sequence is thought to separate the human and chimp genomes. New research published in Genome Biology identifies the subset of sequences that may have driven the evolution of our two species.

 | Experimental evidence reveals that chimpanzees will help other unrelated humans and conspecifics without a reward, showing that they share crucial aspects of altruism with humans. ...> Full Article |
Human resistance to a retrovirus that infected chimpanzees and other nonhuman primates 4 million years ago ironically may be at least partially responsible for the susceptibility of humans to HIV infection today.

| Chimpanzee communities can acquire their own local customs and maintain their own 'multiple-tradition cultures', according to researchers at the University of St Andrews. ...> Full Article |
 | Female chimpanzees can be as violent and demonic as males, shattering the stereotype that males are the more aggressive of the species. ...> Full Article |
 | Researchers at the Yerkes National Primate Research Center, Emory University, have found bonobos and chimpanzees use manual gestures of their hands, feet and limbs more flexibly than they do facial expressions and vocalizations, further supporting the evolution of human language began with gestures as the gestural origin hypothesis of language suggests. This study appears in the current issue of the Proceedings of the National Academy of Sciences. ...> Full Article |
Put a human and a chimpanzee side by side, and it seems obvious which lineage has changed the most since the two diverged from a common ancestor millions of years ago. Such apparent physical differences, along with human speech, language and brainpower, have led many people to believe that natural selection has acted in a positive manner on more genes in humans than in chimps.

Scientists from the University of Illinois at Champaign-Urbana have found that people employed in chimpanzee-focused research and tourism in a park in western Uganda are exchanging gastrointestinal bacteria – specifically Escherichia coli – with local chimpanzee populations. And some of the E. coli strains migrating to chimps are resistant to antibiotics used by humans in Uganda.
