The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
The chimpanzee is on the IUCN Red List as an endangered species. Chimpanzees are legally protected in most of their range and are found both in and outside national parks. Between 172,700 and 299,700 individuals are thought to be living in the wild, [2] a decrease from about a million chimpanzees in the early 1900s. [193]
The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is thus humans ' closest living relative.
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype , [ 1 ] [ 2 ] [ 3 ] and can be found by looking at the chromosomes through a microscope .
The population of the species has radically decreased over the past decade. [8] Silky sifaka: Propithecus candidus: 250 [9] CR [9] [9] Estimate is believed to be a maximum. [9] Tonkin snub-nosed monkey: Rhinopithecus avunculus: 250 [10] CR [10] [10] Barbara Brown's titi: Callicebus barbarabrownae: 260 [11] CR [11] [11] Minimum estimation. [11 ...
Chimpanzees are better suited for walking than orangutans, because the chimp's feet have broader soles and shorter toes. The bonobo has proportionately longer upper limbs and walks upright more often than does the common chimpanzee. Both species can walk upright on two legs when carrying objects with their hands and arms.
Primates exhibit the highest levels of sexual dimorphism amongst mammals, [2] therefore the maximum body dimensions included in this list generally refer to male specimens. Mandrills and baboons are monkeys; the rest of the species on this list are apes.
