Bolivian rainforest study suggests feeding behavior in monkeys and humans have ancient, shared roots
Behavioural ecologists working in Bolivia have found that wild spider monkeys
control their diets in a similar way to humans, contrary to what has been thought up to now. Rather than trying to maximize their daily energy intake, the monkeys
tightly regulate their daily protein intake, so that it s...
Simian foamy virus found in several people living and working with monkeys in Asia
A research team led by University of Washington scientists has found that several people in South and Southeast Asian countries working and living around monkeys

Ugandan monkeys harbor evidence of infection with unknown poxvirus

Moderate prenatal exposure to alcohol and stress in monkeys can cause touch sensitivity
A new study on monkeys

Island monkeys do not recognize big cat calls Monkeys

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes
Neurobiologists at Duke University Medical Center have found the strongest evidence yet that monkeys

Gambling monkeys give insight into neural machinery of risk
Duke University Medical Center neurobiologists have pinpointed circuitry in the brains of monkeys

Rhesus monkeys can assess the visual perspective of others when competing for food
