The team concluded that the conservation of primate habitat is crucial to preventing resource based attacks on humans by primates. The short and simple answer is, our closest cousins, chimpanzees are stronger than humans because our nervous systems exert more control over our muscles. As they grow up, infants begin to walk on their own but continue to hitch a ride on their mothers, increasingly on her back, until they are weaned at about 4 to 5 years old.

How did coyotes become regular city slickers? But that's like a tiger cubthey're also a lot of fun to have.

"He also appeared to have placed projectiles behind, just before he went in after the hay. In all, the scientists collected data on 18 chimpanzee groups and four bonobo groups living in Africa. He further thinks that research on the behavior could shed light on the evolution of stone tool use in humans. The findings run contrary to recent claims that chimps fight only if they are stressed by the impact of nearby human activityand could help explain the origins of human conflict as well.

The study, published in a special issue of The American Journal of Primatology, suggests that while rare, attacks by primates on humans may increase as wild habitat is increasingly converted for agriculture. Large predators need a lot of space, and in a human-dominated world, they need to be able to live alongside humans without conflict. The effect was so strong, the recordings had a similar effect to removing predators from an ecosystem altogether, with reduced predator activity allowing small, would-be prey animals, like mice, to forage more than they normally would. He cautions against drawing any connections to human warfare and suggests instead that the findings could speak to the origins of teamwork. Get more great content like this delivered right to you!
