He further thinks that research on the behavior could shed light on the evolution of stone tool use in humans. "The contrast could not be more stark" between how the two hypotheses fared, says William McGrew, a primatologist at the University of Cambridge in the United Kingdom, who praises the study as a "monumental collaborative effort." "In general people should keep calm, try not to scream and avoid running off or scattering, especially within groups," said Dr Kimberley Hockings from the New University of Lisbon in Portugal, a co-guest editor of the special issue.

NEWS: Zoo Chimp Makes Elaborate Plots to Attack Humans. Usually these animals end up in a cage. Then they resumed their attack. technology (Tech Xplore) and medical research (Medical Xpress), Aggression is a common part of the chimpanzee behavior, whether it's between or within groups. "This is a very important study, because it compiles evidence from many sites over many years, and shows that the occurrence of lethal aggression in chimpanzees is not related to the level of human disturbance," Joan Silk, a professor in the school of Human Evolution and Social Change at Arizona State University, who was not involved in the study, told Live Science in an email. After observing the chimp for days, the scientists also suspect that Santino just also "finds it fun" to bug humans. "And I would think that this is something that comes naturally to them when performing their dominance displays. Osvath said, "What is interesting is that he made these preparations when the visitors were out of sight, and also that he incorporated innovations into the behavior. No one knows for sure why the chimps are attacking children but both curiosity and predatory reasons have been blamed. He cautions against drawing any connections to human warfare and suggests instead that the findings could speak to the origins of teamwork. Attackers use their canines to bite and tear at the victim, so that any body parts that stick out, such as testes and ears, are often ripped off during an attack..

Thankfully, they'll all miss. Instead, attacks were more common at sites with many males and high population densities. For example, when humans cut down forests for farming or other uses, the loss of habitat forces chimps to live in close proximity to one another and to other groups. Here's how to watch.

Related: Chimps seen sucking brains from monkeys' heads. The brutal attack prompted many to wonder what, if anything, provoked the animals? In the process, our chimpanzees have acquired more land and resources that are then redistributed to others in the group.". Osvath additionally believes that the phenomenon taps into "one of the hardest questions in science: how matter (in this case the brain) can appear to be influenced by something that does not exist (the future). 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. Predators see the upright stance and assume humans are tougher than we actually are, according to Hawks.

Forests have, and continue to be, converted to farmland across Africa, which reduces the available habitat for chimpanzees.

But a major new study of warfare in chimpanzees finds that lethal aggression can be evolutionarily beneficial in that species, rewarding the winners with food, mates, and the opportunity to pass along their genes. A chimpanzee gestation period lasts about 230 days or almost 33 weeks, according to the International Union for Conservation of Nature (IUCN). For example, he says, a higher number of males in a group and greater population densitywhich the researchers used as indicators of adaptive strategiescould equally be the result of human disturbances.
