The Strepsithini is a subtribe of primates that includes both the lorises and the Old World monkeys
The Strepsithini is a subtribe of primates that includes both the lorises and the Old World monkeys. Therefore, option a (lorises) and option b (Old World monkeys) are correct choices for the Strepsithini.
Lorises are a group of strepsirrhine primates found in Africa and Asia. They are nocturnal and have large eyes, a wet nose, and a short tail. Lorises belong to the family Lorisidae, which includes the various species of slow lorises and the slender lorises.
On the other hand, Old World monkeys are a group of primates classified in the family Cercopithecidae. They are found in Africa and Asia and include well-known species like baboons, macaques, langurs, and colobus monkeys. Old World monkeys have certain characteristics such as possessing tails (unlike apes), having a relatively complex social structure, and being diurnal (active during the day).
However, the New World monkeys (option c) and the chimpanzees (option d) do not belong to the Strepsithini. New World monkeys, belonging to the family Cebidae, are found in Central and South America. They are known for their prehensile tails and include species like spider monkeys, howler monkeys, and capuchin monkeys.
Chimpanzees, which are the closest living relatives to humans, belong to the tribe Hominini and the genus Pan. They are native to central and western Africa and are known for their sophisticated cognitive abilities and social behavior. However, they are not classified within the Strepsithini subtribe.
Finally, humans (option e) also do not fall under the Strepsithini category. Humans, scientifically known as Homo sapiens, belong to the tribe Hominini along with chimpanzees, bonobos, and other extinct relatives, and are distinct in terms of their evolutionary characteristics, anatomy, and behavior.
In summary, the Strepsithini includes lorises (option a) and Old World monkeys (option b), while New World monkeys (option c), chimpanzees (option d), and humans (option e) do not fall into this subtribe.
