Lend me a flipper
Researchers at Kyoto University's Primate Research Institute, Kindai University, and Kagoshima City Aquarium investigated the cooperative abilities of dolphins. Utilizing a simplified Hirata Task, the team found that dolphins coordinated their behavior to work together on a shared task. Specifically, the 'initiator' would wait on their partner and the 'follower' would coordinate their swimming speed to match the initiator's behavior. (2019-10-28)

Gene enhancer in evolution of human opposable thumb
Scientists have discovered gene enhancer, known as HACNS1, that may have contributed to evolution of uniquely opposable human thumb, and possibly also modifications in ankle or foot that allow humans to walk on two legs, according to paper published in Science, Sept. 5, 2008. (2008-09-04)

Chimpanzees help researchers improve machine learning of animal simulations
Researchers at The University of Manchester are using computer simulations of chimpanzees to improve not only our understanding of how the animals walk, but also the technology we use to do it. (2018-03-06)

Viruses can evolve in parallel in related species
Viruses are more likely to evolve in similar ways in related species -- raising the risk that they will 'jump' from one species to another, new research shows. (2018-04-12)

Kent State research group publishes analysis of primate brains in top science journal
How different are human brains compared to the brains of other primates such as chimpanzees, gorillas and monkeys? Researchers in Kent State University's College of Arts and Sciences recently co-authored an article with more than 30 scientists, led by Yale University, from the United States, Italy and Spain in the journal Science that describes some of the small, yet distinct differences between the species in how individual cells function and form connections. (2017-11-30)

Dogs, toddlers show similarities in social intelligence
University of Arizona researcher Evan MacLean, director of the Arizona Canine Cognition Center, found that dogs and 2-year-old children show similar patterns in social intelligence, much more so than human children and one of their closest relatives: chimpanzees. The research could help scientists better understand how humans evolved socially. (2017-02-27)

How does HIV escape cellular booby traps?
Utilizing the humanized mouse model, researchers find that simian immunodeficiency virus, SIV, evolved to infect humans as HIV via Vpu evolving to inhibiting tetherin. (2018-04-04)

Comparison of primate brains hints at what makes us human
A detailed comparative analysis of human, chimpanzee and macaque brains reveals elements that make the human brain unique, including cortical circuits underlying production of the neurotransmitter dopamine. (2017-11-23)

Small but distinct differences among species mark evolution of human brain
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new Yale-led study has found. (2017-11-23)

Unlike people, bonobos don't 'look for the helpers'
By the age of three months, human babies can already follow Mr. Rogers' advice to 'look for the helpers.' In fact, human infants naturally show a strong preference for individuals who help rather than hinder others. Now, a study reported in Current Biology finds that the same cannot be said of bonobos. While bonobos are similarly adept in discriminating helpers from hinderers, they show the opposite bias, consistently favoring hinderers over helpers. (2018-01-04)

Virginia Tech researchers find human virus in chimpanzees
After studying chimpanzees in the Tanzania's Mahale Mountains National Park for the past year, Virginia Tech researcher Dr. Taranjit Kaur and her team have evidence that chimpanzees are becoming sick from viral infectious diseases they have likely contracted from humans. (2008-06-03)

Chimpanzee self-control is related to intelligence, Georgia State study finds
As is true in humans, chimpanzees' general intelligence is correlated to their ability to exert self-control and delay gratification, according to new research at Georgia State University. (2018-02-08)

Anti-virus protein in humans may resist transmission of HIV-1 precursor from chimps
In humans, an anti-virus protein known as APOBEC3H may defend against cross-species transmission from chimpanzees of the virus that gave rise to HIV-1. Zeli Zhang of Heinrich-Heine-Universität Düsseldorf, Germany, and colleagues present this finding in a new PLOS Pathogens study. (2017-12-21)

Bonobo and chimpanzee gestures share multiple meanings
Two closely related great ape species, the bonobo and chimpanzee, use gestures that share the same meaning researchers have found. (2018-02-27)

Dogs share food with other dogs even in complex situations
Dogs also share their food, albeit mainly with four-legged friends rather than strangers. A new study conducted by behavioral biologists from the Messerli Research Institute at Vetmeduni Vienna has now confirmed this prosocial behavior among canines. The more complex methodology of the study, however, showed that the experimental set-up has an impact on the dogs' behavior and that even the mere presence of another dog makes the animals more generous. (2017-01-27)

Why do chimpanzees throw stones at trees?
Newly discovered stone tool-use behavior and accumulation sites in wild chimpanzees are reminiscent to human cairns. (2016-03-03)

Chimp study reveals how brain's structure shaped our evolution
Chimpanzee brains may be more different from those of humans than was previously thought, according to new research that sheds light on our evolution. (2017-11-15)

Chimp females who leave home postpone parenthood
Female chimps that lack supportive friends and family wait longer to start having babies, Duke University researchers find. An analysis of more than 50 years' worth of daily records for female chimpanzees in Gombe National Park in Tanzania indicates that would-be moms who leave home or are orphaned take roughly three years longer to start a family. (2017-11-20)

'Uniquely human' muscles have been discovered in apes
Muscles believed to be unique to humans have been discovered in several ape species, challenging long-held anthropocentric theories on the origin and evolution of human soft tissues. This questions the view that certain muscles evolved to provide special adaptations for human traits, such as walking on two legs, tool use, and sophisticated vocal communication and facial expressions. The findings highlight that thorough knowledge of ape anatomy is necessary for a better understanding of human evolution. (2018-05-23)

Chimpanzees can learn how to use tools without observing others
New observations have lead researchers to believe that chimpanzees can use tools spontaneously to solve a task, without needing to watch others first. (2017-09-28)

Massive study across western equatorial Africa finds more gorillas and chimpanzees than expected
A massive decade-long study of Western Equatorial Africa's gorillas and chimpanzees has uncovered both good news and bad about our nearest relatives. The good news: there are one third more western lowland gorillas and one tenth more central chimpanzees than previously thought. The bad news: the vast majority of these great apes (80 percent) exist outside of protected areas, and gorilla populations are declining by 2.7 percent annually. (2018-04-25)

Study identifies energy efficiency as reason for evolution of upright walking
A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking. (2007-07-16)

Chimpanzee deaths in Uganda pinned on human cold virus
In the wild, chimpanzees face any number of dire threats, ranging from poachers to predators to deforestation. That's why scientists, investigating an outbreak of respiratory disease in a community of wild chimpanzees in Uganda's Kibale National Park, were surprised and dismayed to discover that a human 'common cold' virus known as rhinovirus C was killing healthy chimps. (2017-12-13)

Adult chimpanzees play more than adult lowland gorillas in captivity
Play is more frequent in captive adult chimpanzees than in captive adult lowland gorillas, according to a study published March 7, 2018 in the open-access journal PLOS ONE by Giada Cordoni and Elisabetta Palagi from Univerity of Pisa in collaboration with Ivan Norscia from University of Turin. (2018-03-07)

Reconstruction of ancient chromosomes offers insight into mammalian evolution
Researchers have gone back in time, at least virtually, computationally recreating the chromosomes of the first eutherian mammal, the long-extinct, shrewlike ancestor of all placental mammals. (2017-06-21)

Aging bonobos in the wild could use reading glasses too
As people age, they often find that it's more difficult to see things up close. Reading a newspaper suddenly requires a good pair of reading glasses or bifocals. Now, researchers reporting in the Cell Press journal Current Biology on Nov. 7 find that the same goes for bonobos, one of human's closest primate relatives along with chimpanzees, even though they obviously don't read. (2016-11-07)

Chimpanzees start using a new tool-use gesture during an alpha male take over
Similar to humans, non-human primates combine gestures, facial expressions, and vocalizations in various ways to communicate effectively. Researchers of the Max Planck Institute for Evolutionary Anthropology investigated one such signal, the 'leaf clip' gesture, which re-emerged in a wild chimpanzee group during an alpha takeover. Importantly, the gesture was produced only by adult male chimpanzees, immediately preceded their pant hoot vocalizations and was associated with acoustic changes in those calls. (2018-06-28)

New 13-million-year-old infant skull sheds light on ape ancestry
The discovery in Kenya of a remarkably complete fossil ape skull reveals what the common ancestor of all living apes and humans may have looked like. (2017-08-09)

Long-term logging study demonstrates impacts on chimpanzees and gorillas (Republic of Congo)
Research has shown human disturbance can have detrimental effects on great ape populations but now, due to a study published in Biological Conservation on Nov. 27 by Lincoln Park Zoo, there is evidence showing how selective logging impacts chimpanzees and gorilla populations differently by utilizing data collected before, during and after timber extraction. (2017-11-27)

In a last 'stronghold' for endangered chimpanzees, survey finds drastic decline
In a population survey of West African chimpanzees living in Côte d'Ivoire, researchers estimate that this endangered subspecies has dropped in numbers by a whopping 90 percent since the last survey was conducted 18 years ago. The few remaining chimpanzees are now highly fragmented, with only one viable population living in Taï National Park, according to a report in the Oct. 14 issue of Current Biology, a Cell Press publication. (2008-10-13)

Why humans outlive apes
The same evolutionary genetic advantages that have helped increase human lifespans also make us uniquely susceptible to diseases of aging such as cancer, heart disease and dementia, reveals a study to be published in a special PNAS collection on (2010-01-25)

Fish provide insight into the evolution of the immune system
New research reveals how immune systems can evolve resistance to parasites. The study published in Nature Communications, solves the enigma of how species can adapt and change their immune system to cope with new parasitic threats -- whilst at the same time showing little or no evolutionary change in critical immune function over millions of years. It help to explain why we humans have some immune genes that are almost identical to those of chimpanzees. (2017-11-06)

How infighting turns toxic for chimpanzees
How did a once-unified community of chimpanzees in Gombe National Park, Tanzania, end up at each other's throats? In a new study, researchers mapped the chimps' social networks at different periods leading up to the split to pinpoint when relations began to fray, and test ideas about what caused the rift. The most likely culprit was a power struggle among three top-ranking males, which was made worse by a shortage of fertile females, results show. (2018-03-26)

Rwanda conservation effort to link isolated chimps to distant forest
Some 15 chimpanzees facing extinction in an isolated Rwandan forest have a greater chance for survival thanks to one of Africa's most ambitious forest restoration efforts ever. (2008-03-18)

Researchers gain insight into infant handling by young bonobos
University of Oregon anthropologist Klaree Boose followed her intuition about her observations of bonobos at a US zoo. She now theorizes that young females of the endangered ape species prepare for motherhood and form social bonds by helping mothers take care of infants. (2018-06-19)

Congo plans to safeguard biodiversity with new protected areas
The Republic of Congo announced today plans to expand its protected area network for the purpose of further conserving the region's immense biodiversity, one of the key goals of the 7th Conference of the Parties for the Convention on Biological Diversity (COP-7). (2004-02-19)

Genetic opposites attract when chimpanzees choose a mate
Duke University researchers find that chimpanzees are more likely to reproduce with mates whose genetic makeup most differs from their own. Many animals avoid breeding with parents, siblings and other close relatives, researchers say. But chimps are unusual in that even among virtual strangers they can tell genetically similar mates from more distant ones. Chimps are able to distinguish degrees of genetic similarity among unfamiliar mates many steps removed from them in their family tree. (2017-01-11)

Killer whales share personality traits with humans, chimpanzees
Killer whales display personality traits similar to those of humans and chimpanzees, such as playfulness, cheerfulness and affection, according to new research published by the American Psychological Association. (2018-11-15)

What grosses out a chimpanzee?
Chimps show increased latencies to feed, and tendencies to maintain greater distances from possible contaminants and/or outright refusals to consume food in test conditions, hinting at the origins of disgust in humans. (2017-11-17)

What gorilla poop tells us about evolution and human health
A study of the microbiomes of wild gorillas and chimpanzees offers insights into the evolution of the human microbiome and might even have implications for human health. The research project was led by scientists at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health. Findings appear in the journal Nature Communications. (2018-05-03)
