The blue monkeys painted on the walls of Akrotiri on the Greek island of Santorini are among many animals found in the frescoes of this 3,600-year-old city. Historians have studied the murals for decades since they were unearthed in the 1960s and 1970s on the island, which was once known as Thera. But when we and a team of other primatologists recently examined the paintings, we realized the monkeys could provide a clue that the Bronze Age world was much more globalized than previously thought.

In mammals, pair bonds are very rare, one of the few exceptions being the red titi monkeys of South America. These relatively small tree dwellers live in pairs or small family groups and are characterized by the fact that the males take intensive care of their offspring. A team of researchers from the German Primate Center—Leibniz Institute for Primate Research has now investigated how pair relationships work in titi monkeys. Their results support the so-called "male-services hypothesis": […]

First came the flames, a raging firestorm propelled by 50 mph (80 kph) wind gusts that incinerated Kelsey Norton's house and killed 85 people in her community.

Deforestation is changing the way monkeys communicate in their natural habitat, according to a new study.
