![]() 40 million years ago New World monkeys diverged from Old World Monkeys.Both the lemur-like and the tarsier-like primates were represented by several species in the Eocene fossil record of southern California.Two main primate suborders appeared before 50 million years ago:.Fossils, however, suggest a somewhat younger date for emergence of primate-like mammals at about 65-57 million years ago (Paleocene) in Europe and North America.Several genetic studies each examining different aspects of DNA concluded that primate-like mammals diverged from other mammals some 90 million years ago, during the Cretaceous Period.Local Names: "Eja", "Engombe" (Limongo names) "Mokumbusu" (Lingala name).troglodytes and retaining juvenile traits in adulthood bonobos, however are not smaller than all chimpanzees), dwarf chimpanzee, gracile chimpanzee Pygmy chimpanzee (based on Coolidge's 1933 species description citing Pan paniscus as being somewhat smaller than P.Bonobo (may be a mispronunciation of Bolobo, a town near the Zaire River region of early specimen collection).The genetic similarity between bonobos, chimpanzees, and humans is so high that at least one taxonomist has suggested placing them all in the same genus ( Homo) (Wildman et al 2003).2012) and 98.8% identical with the chimpanzee genome ( CSAC 2005). Recent DNA sequencing data show that the human genome is 98.7% identical with the bonobo genome ( Prüfer et al.(Maclaurin & Sterelny 2008, Kaessmann et al 1999) Together they are humans' closest relatives. Bonobos and chimpanzees are sister species, and each is equally closely related to humans.Bonobos initially described incorrectly as subspecies of the chimpanzee, Pan satyrus (Schwarz 1929) reclassified as separate species, Pan paniscus, four years later (Coolidge 1933).Bonobos (Pan paniscus) and chimpanzees (Pan troglodytes)are distinct species, according to both morphological and genetic data collected in many recent studies (Won & Hey 2005).Other taxonomists would place the orangutans in their own separate family, Pongoidae. Wilson & Reeder (2005) would eliminate the separate subfamilies and group all four together as hominids. ![]() Groves (1989) recommended that the four great ape genera be combined into one family, Hominidae, with orangutans in a separate subfamily from the other three.Bonobos are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Primates, family Hominidae. The few thousand that remain in the wild are hunted by humans, and their habitat is being fragmented by encroaching human settlement, agriculture, and logging operations. The bonobo is listed as an endangered species. ![]() Both bonobos and common chimpanzees have been able to learn the meanings of many human words (although they cannot vocalize them), and they can be trained to communicate with humans by using sign language or symbol boards. Bonobos are generally less violent than common chimpanzees, and there are fewer conflicts between neighboring bonobo communities. Moreover, both males and females appear to use sexual contact as a means of communication and a way to ease tensions that might otherwise erupt into conflict, though there is evidence to suggest this is much more common in captive, rather than wild, bonobos. Their groups are usually larger than those of common chimpanzees, however, and often the females are closely bonded and tend to dominate males. The bonobo has a more slender body build than the common chimpanzee, but there is considerable overlap in overall size (head-and-body length and weight) among individuals of the two species.īonobos share many behavioral traits with common chimpanzees e.g., they tend to associate in groups, are day-active, build sleeping nests in trees, and eat mostly fruit and other vegetable matter. ![]() paniscus (sometimes called the pygmy chimpanzee), is found only in the Congo (Kinshasa) S of the Congo River. troglodytes, lives in forests across most of equatorial Africa, the bonobo, P. Bonobo, smaller of two species of chimpanzee, genus Pan. ![]()
