New monkey business.A new kind of monkey is giving scientists a lot to think about. Two groups of researchers independently discovered the rare creature in different forests in Tanzania last year (see "New Mammals The class Mammalia (the Mammals) is divided into two subclasses based on reproductive techniques: egg laying mammals (the Monotremes); and mammals which give live birth. The latter subclass is divided into two infraclasses: pouched mammals (the marsupials); and the placental mammals. "). They classified the shy animal as a mangabey mangabey: see monkey. , a type of primate primate, member of the mammalian order Primates, which includes humans, apes, monkeys, and prosimians, or lower primates. The group can be traced to the late Cretaceous period, where members were forest dwellers. , and gave it the species name Lophocebus kipunji. The monkey, however, may not be a mangabey after all. New evidence suggests that it belongs to a brand new genus (a category that's one step broader than species). It may fit in the primate family tree closer to baboons than it does to mangabeys mangabeys dark-colored, long-snouted Old World monkeys with a wide distribution and common as zoo specimens, e.g. crested mangabey (Cercocebus albigena). . When the scientists named L. kipunji, they had seen it in the wild and taken pictures of it. But they had never been able to study one up close. Then, last August, a Tanzanian farmer found a dead kipunji in a trap that he had set to catch animals that tried to eat his crops. To better understand its place in the primate family tree, a group of international scientists collected samples of the genetic material DNA DNA: see nucleic acid. DNA or deoxyribonucleic acid One of two types of nucleic acid (the other is RNA); a complex organic compound found in all living cells and many viruses. It is the chemical substance of genes. from the dead animal. Analyses of the DNA suggested that this new monkey is more closely related to baboons than it is to mangabeys. Comparisons of the young male monkey's body to those in the baboon baboon, any of the large, powerful, ground-living monkeys of the genus Papio, also called dog-faced monkeys. Five subspecies live in Africa, with one species extending into the Arabian peninsula. collection at Chicago's Field Museum, however, told a different story. L. kipunji just didn't fit in. It didn't look like a baboon. If it's not a mangabey, and it's not a baboon, then what is it? The researchers propose a new genus called Rungwecebus. The genus name refers to Mt. Rungwe, where this monkey was first observed. So, the monkey's name is now Rungwecebus kipunji. Scientists continue to debate the decision to create a new genus, but if it sticks, it would be the first new monkey genus to be recognized since the 1920s.--E.
