Human-like altruism shown in chimpanzees
Debates about altruism are often based on the assumption that it is either unique to humans or else the human version differs from that of other animals in important ways. view more (2007-06-26)
Chimpanzees Can Transmit Cultural Behavior to Multiple "Generations"
or the first time, researchers have shown chimpanzees exhibit generational learning behavior similar to that in humans. Unlike previous findings that indicated chimpanzees simply conform to the social norms of the group, this study shows behavior and traditions can be passed along a chain of individual chimpanzees. view more (2006-08-30)
Third primate genome, the rhesus macaque, helps illuminate what makes us human
Researchers have sequenced the genome of the relatively ancient rhesus macaque (Macaca mulatta), providing perspective into how humans are genetically different from our primate relatives. view more (2007-04-13)
Evidence that up to 10 percent of human genome may have changed very recently revealed by CU researchers
A Cornell study of genome sequences in African-Americans, European-Americans and Chinese suggests that natural selection has caused as much as 10 percent of the human genome to change in some populations in the last 15,000 to 100,000 years, when people began migrating from Africa. view more (2007-07-12)
Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals
In the most thorough study to date of the Neanderthal genome, scientists suggest an early human-Neanderthal split. The two species have a common ancestry, say the authors, but do not share much else after evolving their separate ways. view more (2006-11-16)
Researchers find first conclusive evidence of Alzheimer's-like brain tangles in nonhuman primates
Researchers at the Yerkes National Primate Research Center, Emory University, have discovered the first conclusive evidence of Alzheimer's-like neurofibrillary brain tangles in an aged nonhuman primate. view more (2008-05-15)
Lack of potential mates has lead to "sloppy" gene control and risk of disease for humans
Our evolutionary ancestors' lack of choice in the mating game has left modern humans exposed to disease, according to new research published in the journal PLOS Biology tomorrow (Tuesday 25 January 2005). view more (2005-01-24)
The origin of human bipedalism
While no one has an authoritative answer, anthropologists have long theorized that early humans began walking on two legs as a way to reduce locomotor energy costs. view more (2007-07-17)
Clues to future evolution of HIV come from African green monkeys
Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to new research from The University of Arizona in Tucson. view more (2007-07-17)
Flipped genetic sequences illuminate human evolution and disease
By comparing the human genome with that of the chimpanzee, man's closest living relative, researchers have discovered that chunks of similar DNA that have been flipped in orientation and reinserted into chromosomes are hundreds of times more common in primates than previously thought. view more (2005-10-26)
Zoo volunteers help explain mysteries of the genome
As the University of Leicester approaches the 25th anniversary of the discovery of DNA fingerprinting (September 10), Leicester geneticists interested in a particular type of DNA are receiving some help from an unusual band of assistants. view more (2009-09-08)
University of Sussex biologists estimate the pace of evolution
Scientists at the University of Sussex have provided the key to resolving a 30-year-old controversy in evolutionary biology: what proportion of the differences between similar species came about as a result of natural selection, and how many are just the result of 'random genetic drift'. In a paper in this week's issue of Nature (28 February),... view more... (2002-02-26)
Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. view more (2008-08-05)
The roots of civilization trace back to ... roots
About five to seven million years ago, when the lineage of humans and chimpanzees split, edible root plants similar to rutabagas and turnips may have been one of the reasons. view more (2005-09-19)
Comparing Chimp, Human DNA
Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study. view more (2006-10-16)
Fair Play in Chimpanzees
New research from the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany shows that unlike humans, chimpanzees conform to traditional economic models. The research, conducted by Keith Jensen, Josep Call and Michael Tomasello, used a modification of one of the most widely used and accepted economic tools, the ultimatum game... view more...

Man's best friend lends insight into human evolution
Flexibly drawing inferences about the intentions of other individuals in order to cooperate in complex tasks is a basic part of everyday life that we humans take for granted. view more (2007-03-02)
Ebola outbreaks killing thousands of gorillas and chimpanzees
Why have large outbreaks of Ebola virus killed tens of thousands of gorillas and chimpanzees over the last decade? Observations published in the May issue of The American Naturalist provide new clues, suggesting that outbreaks may be amplified by Ebola transmission between ape social groups. view more (2007-04-17)
Charting the path of the deadly Ebola virus in central Africa
Over the past ten years, separate outbreaks of the deadly Zaire strain of Ebola virus (ZEBOV) have killed hundreds of humans and tens of thousands of great apes in Gabon and the Republic of Congo-which harbor roughly 80% of the last remaining wild gorilla and chimpanzee populations. view more (2005-10-25)
Orangutans unique in movement through tree tops
Movement through a complex meshwork of small branches at the heights of tropical forests presents a unique challenge to animals wanting to forage for food safely. view more (2009-07-28)
