The animal closest to human beings in their genetic makeup and habits is a monkey or an ape. Humans have been said to evolve from certain species of apes via natural selection.
But what is interesting is that those apes who did not evolve to become humans share a lot of similarities with us. Monkeys have very similar anatomy to humans.
Apart from this, these Taiwanese primates are pretty intelligent, fast, and catch up really easily. One such species of monkey we will be discussing in this fact file is a Formosan rock macaque also known as Formosan rock monkey. This species of monkey is native to Taiwan and is newly introduced on the island of Japan.
Robert Swinhoe in 1862 first described these monkeys. These monkeys belong to the genus Macaca, the genus of gregarious Old-World monkeys, and their binomial name is Macaca cyclopis.
