Most people will have seen at least one headline over the last couple of years describing animal attacks on humans. This needn't include the elephant from... more
The cryoEM structure of a simian immunodeficiency virus protein bound to primate proteins shows how a mutation in early humans allowed our ancestors to escape infection while monkeys and apes did not. SIV's Nef... more
New research on one of the oldest and most complete fossil primate skulls from South America shows instead that the pattern of brain evolution in this group was far more... more
It has long been thought that the brain size of anthropoid primates—a diverse group of modern and extinct monkeys, humans, and their nearest kin—progressively increased over time. New research on... more
Understanding of ancestral conditions for anthropoids has been hampered by the paucity of well-preserved early fossils. Here, we provide an unprecedented view... more
Neuroscientists have published an updated view on the primate brain's visual system organization. They found that parts of the primate visual system may work differently than previously thought. more
Impulsiveness in adolescence isn't just a phase, it's biology. And despite all the social factors that define our teen years, the human brain and the brains... more
Communication gestures used by humans and our primate relatives are providing clues about how our species' ability to use spoken language evolved. more
Boosting a single molecule in the brain can change "dispositional anxiety," the tendency to perceive many situations as threatening, in nonhuman primates, researchers from... more
Hedgehogs, rabbits, primates and even giraffe have all benefited in the evolutionary race due to their ability to adapt their metabolism to cope with a changing climate, according... more
Boosting a single molecule in the brain can change 'dispositional anxiety,' the tendency to perceive many situations as threatening, in nonhuman primates, researchers have found. The molecule, neurotrophin-3, stimulates neurons to grow... more
Recent primate research has had a heavy focus on a few charismatic species and nationally protected parks and forests, leaving some lesser known primates and their habitats at risk. more
"Birds of a feather flock together," or rather "opposites attract"? A recently published study on male macaques in Thailand speaks for the former: Behavioral biologists from the German Primate Centre—Leibniz... more
Recent primate research has had a heavy focus on a few charismatic species and nationally protected parks and forests, leaving some lesser known primates and their habitats at risk, according researchers at... more
A new species of marmoset has been discovered in the southwest of Pará State in Brazil, a discovery that, while thrilling, already has conservationists worrying about its long-term... more
The essential everyday task of making appropriate choices is a process controlled mainly by the basal ganglia. To this end, subjects need not only... more
Despite their large body size, gorillas are known to have a vegetarian diet consisting almost exclusively of leafy vegetation and fruit. Their teeth are large and high-crested when compared to other great apes, which is usually... more
An initial infection with dengue virus did not prime monkeys for an especially virulent infection of Zika virus, according to a new study. Nor did a... more
Most accounts of behavior in nonhuman animals assume that they make choices to maximize expected reward value. However, model-free reinforcement learning based on reward associations cannot account for... more
Tropical rainforests store large quantities of carbon dioxide, produce oxygen and provide habitats for many animal and plant species. If these ecosystems, which are so important for the global climate and biodiversity, are destroyed, they will recover very... more
