Question # 19
Anthropologists who study orangutans,distant cousins of the human race find in the animals behaviour hints of how our earliest ancestors may have lived.It has long been accepted that primates originally dwelt in the treetops and only migrated to the ground as forests began to dwindle.While to a certain extent,all primates excepts humans spend at least some time dwelling in trees,the orangutan hardly ever ventures to the forest floor.Adult orangutans can grow as heavy as 330 pounds and live for decades,requiring copious amounts of fruit simply to stay alive.Thus,they become very jealous of the territory where they find their food.Compounding this territoriality are the breeding habits of orangutans since females can only breed every few years and,like humans give birth not to litters but single offspring.Consequently,orangutans are solitary,territorial animals who have difficulty foraging in any part of the forest where they were not raised Orangutans take from poachers by customs agents undergo incredible hardship on their return to the wild.Incorrectly relocating a male orangutan is especially problematic,often ending in the animal's death at the hands of a rival who sees not only his territory but also the females of his loosely knit community under threat from an outsider.while humans like chimpanzees are more gregarious and resourceful than orangutans the latter provide anthropologists with useful information about the behaviour of pre hominid primates and how apelike behaviour influenced out ancestors search for the food and family beneath the forest's canopy.vi.Which of the following can be inferred about differences between the behaviour of orangutans and that of other ape species?
