Gorilla study gives social clues
The western gorilla lives peacefully in human-like social groups, a study shows. Only the mountain gorilla, which is known for its aggressive behaviour, chest-beating and fighting, has been widely observed in the wild until now. But the new research suggests the western gorilla, another gorilla species, interacts peacefully when it comes into contact with other apes. The study, published in the journal Current Biology, may give an insight into the social world of early humans.
