Researchers have developed formulas that can calculate the body size of a primate based on the root size of its teeth. The formulas could allow researchers to make use of partial and incomplete fossils in order to learn how ancient primates – including human ancestors – interacted with their environment.
Songbirds share the human sense of rhythm, but it is a rare trait in non-human mammals.
Some primate species may express grief over the death of their infant by carrying the corpse with them, sometimes for months, according to a new UCL-led study – with implications for our understanding of how non-human animals experience emotion.
A research team that includes Anthropology researchers from Stony Brook University has used 14 years of demographic data on multiple groups of wild geladas to determine that mid-size group living is best for fitness, essentially optimizing survival and reproduction.
Scientists have confirmed the species and origin of a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago. They escaped from the Dania Chimpanzee Farm in 1948 and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida. The facility acted as a zoo and also provided primates imported from Africa as research subjects in the development of the polio vaccine and other medical research.
Wild orangutans are known for their ability to survive food shortages, but scientists have made a surprising finding that highlights the need to protect the habitat of these critically endangered primates, which face rapid habitat destruction and threats linked to climate change. Scientists found that the muscle mass of orangutans on the island of Borneo in Southeast Asia was significantly lower when less fruit was available. That’s remarkable because orangutans are thought to be especially good at storing and using fat for energy, according a Rutgers-led study in the journal Scientific Reports.
A new study out of the University of Chicago and the University of Illinois Urbana-Champaign in humans, chimpanzees, rhesus macaques and baboons has found key differences in early gene expression in response to pathogen exposure, highlighting the importance of choosing the right animal model for the right questions.
A new study published Feb. 24 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. These creatures lived less than 150,000 years after the Cretaceous-Paleogene mass extinction event that killed off non-avian dinosaurs and saw the rise of mammals.
Hard plant foods may have made up a larger part of early human ancestors’ diet than currently presumed, according to a new experimental study of modern tooth enamel from Washington University in St. Louis. The results have implications for reconstructing diet, and potentially for our interpretation of the fossil record of human evolution, researchers said.
Some primates can carry SIV, a virus resembling HIV, lifelong and yet not develop AIDS. They are able to repair SIV damage to intestinal mucous tissues and avoid escape of gut bacteria and other events leading to immune system exhaustion. The findings offer clues for new HIV treatments
In a recent article, the Washington Post discussed how the growth of the chocolate industry in Western Africa is leading to rapid deforestation. In a 2015 study, an Ohio State University anthropologist and his colleagues documented how illegal cocoa farms…
