prehistoric human beings have been known to eat elephants, as recent findings of animal remains in central china show. the elephant is now a protected animal, and consumption is prohibited around the world.
v. monkey
a monkey is any member of two of the three groupings of simian primates. these two groupings are the new world and old world monkeys. because of their similarity to monkeys, apes such as chimpanzees and gibbons are sometimes incorrectly called monkeys. also, a few monkey species have the word “ape.” in their common name. because they are not a single coherent group, monkeys do not have any important characteristics that they all share and are not shared with the remaining group of simians, the apes.
monkeys range in size from the pygmy marmoset, at 10 cm (4 inch) long (plus tail) and 120 g (4 oz) in weight to the male mandrill, almost 1 metre (3 ft) long and weighing 35 kg (75 lb). some are arboreal (living in trees), some live on the savanna; some eat fruit, some eat leaves, and some eat insects; although most have tails (sometimes prehensile), others do not; some have trichromatic colour vision like that of humans, others are dichromats or monochromats. although both the new and old world monkeys, like the apes, have forward facing eyes, the faces of old world and new world monkeys look very different. to understand the monkeys, therefore, it is necessary to study the characteristics of the different groups individually.
