Primates have helped people to accomplish many great things such as travel to outer space and find medicines that cure terrible diseases. Biologically they belong to the same order as mankind, and thanks to this connection, scientists gain priceless information by studying them. The Russian Academy of Medical Sciences’ Research Institute of Medical Primatology is located in the village of Vesyoloye, forty kilometres from the southern city of Adler. Here 4,200 monkeys live in open-air cages. There are 20 species of monkeys, including pig-tailed, rhesus, Javan and brown macaques, as well as green monkeys and various species of baboons. Such a wide variety of species can’t even be found at the zoo. The primates living in this environment are here for a much different reason than those at the zoo: To help mankind study the world around us.
