The generic name, Micropithecus, is derived from the Greek Words μικρός (ancient Greek pronounced mikrós, "small") and πίθηκος (pronounced píthēkos, "monkey"). Micropithecus thus means "small ape", referring to the fact that the fossils of this genus are among the smallest fossil apes discovered.
In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or anthropoids – were grouped under Anthropoidea (/ ˌ æ n θ r ə ˈ p ɔɪ d i. ə /; from Ancient Greek ἄνθρωπος (ánthrōpos) 'human' and -οειδής (-oeidḗs) 'resembling, connected to, etc.'), while the strepsirrhines and tarsiers were grouped under the ...
"Ape", from Old English apa, is a word of uncertain origin. [b] The term has a history of rather imprecise usage—and of comedic or punning usage in the vernacular.Its earliest meaning was generally of any non-human anthropoid primate, as is still the case for its cognates in other Germanic languages.
Its teeth were small relative to body size. The lack of a diastema (gap) between the second incisor and first premolar of the mandible indicates that Oreopithecus had canines of size comparable to the rest of its dentition. In many primates, small canines correlate with reduced inter-male competition for access to mates and less sexual dimorphism.
They then passed the tooth along to William K. Gregory and Dr. Milo Hellman, who agreed that the tooth belonged to an anthropoid ape more closely related to humans than to other apes. Only a few months later, an article was published in Science announcing the discovery of a manlike ape in North America. [ 1 ]
Primates are generally thought to have evolved from a small, unspecialized mammal, which probably fed on insects and fruits. However, the precise source of the primates remains controversial and even their arboreal origin has recently been questioned. [1]
A third reason is that, despite accepting that modern humans had emerged by evolution, many anthropologists believed that the genus Homo had split from the great apes as long as 30 million years ago and so felt uneasy about accepting that humans had a small-brained, ape-like ancestor, like Australopithecus africanus, only two million years ago.
[6]: 193 But it is likely that it was a small animal, probably weighing only 12 kilograms (26 lb). This contradicts previous theories that they were the size of chimpanzees and that apes moved to hang and to swing from trees to get off the ground because they were too big. There might have been an arms race in brachiating to reach the best food ...
