Gorilla
Gorillas are primarily herbivorous, terrestrial great apes that inhabit the tropical forests of equatorial Africa. The genus ''Gorilla'' is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 96 to 99% depending on what is included, and they are the next closest living relatives to humans after the chimpanzees. Gorillas are the largest living primates, reaching heights between , weights between , and arm spans up to , depending on species and sex. They tend to live in troops, with the leader being called a silverback. The eastern gorilla is distinguished from the western by darker fur colour and some other minor morphological differences. Gorillas tend to live 35–40 years in the wild. Gorillas' natural habitats cover tropical or subtropical forest in Sub-Saharan Africa. Although their range covers a small percentage of Sub-Saharan Africa, gorillas c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Gorilla
The mountain gorilla (''Gorilla beringei beringei'') is one of the two subspecies of the eastern gorilla. It is listed as endangered by the IUCN . There are two populations: One is found in the Virunga Mountains, Virunga volcanic mountains of Central Africa, Central/East Africa, within three National Parks: Mgahinga Gorilla National Park, Mgahinga, in southwest Uganda; Volcanoes National Park, Volcanoes, in northwest Rwanda; and Virunga National Park, Virunga, in the eastern Democratic Republic of Congo (DRC). The other population is found in Uganda's Bwindi Impenetrable National Park. Some primatologists speculate the Bwindi population is a separate subspecies, though no description has been finalized. The latest population count, released in 2019, revealed there to be approximately 1060 mountain gorillas in the wild. Evolution, taxonomy, and classification Mountain gorillas are descendants of ancestral monkeys and apes found in Africa and Arabia during the start of the Oligo ...

Western Lowland Gorilla
The western lowland gorilla (''Gorilla gorilla gorilla'') is one of two Critically Endangered subspecies of the western gorilla (''Gorilla gorilla'') that lives in Montane ecosystems#Montane forests, montane, Old-growth forest, primary and secondary forest, secondary forest and lowland swampland in central Africa in Angola (Cabinda Province), Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea and Gabon. It is the nominate subspecies of the western gorilla, and the smallest of the four gorilla subspecies. The western lowland gorilla is the only subspecies kept in zoos with the exception of Amahoro (gorilla), Amahoro, a female eastern lowland gorilla at Antwerp Zoo, and a few mountain gorillas kept captive in the Democratic Republic of the Congo. Description The western lowland gorilla is the smallest subspecies of gorilla but still has exceptional size and strength. This species of gorillas exhibits pronounced sexual ...

Western Gorilla
The western gorilla (''Gorilla gorilla'') is a great ape found in Africa, one of two species of the hominid genus ''Gorilla''. Large and robust with males weighing around , the species is found in a region of midwest Africa, geographically isolated from the eastern gorilla (''Gorilla beringei''). The hair of the western species is significantly lighter in color. The western gorilla is the second largest living primate after the eastern gorilla. Two subspecies are recognised: the western lowland gorilla (''Gorilla gorilla gorilla'') is found in most of West Africa; while the Cross River gorilla (''Gorilla gorilla diehli'') is limited to a smaller range in the north at the border of Cameroon and Nigeria. Both subspecies are listed Critically Endangered. Taxonomy A formal description of the species was provided by Thomas Savage in 1847, allying the new species to an earlier description of the chimpanzee as ''Troglodytes gorilla'' in a group of eastern simians he referred to a ...

Eastern Lowland Gorilla
The eastern lowland gorilla (''Gorilla beringei graueri'') or Grauer's gorilla is a Critically Endangered subspecies of eastern gorilla endemic to the mountainous forests of eastern Democratic Republic of the Congo. Important populations of this gorilla live in the Kahuzi-Biéga National Park, Kahuzi-Biega and Maiko National Parks and their adjacent forests, the Tayna Gorilla Reserve, the Usala forest and on the Itombwe Massif. It is the largest of the four gorilla subspecies. It has a jet black coat like the mountain gorilla (''Gorilla beringei beringei''), although the hair is shorter on the head and body. The male's coat, like that of other gorillas, greys as the animal matures, resulting in the designation "silverback". There are far fewer eastern lowland gorillas compared to western lowland gorillas. According to a 2004 report there were only about 5,000 eastern lowland gorillas in the wild, down to fewer than 3,800 in 2016, compared to over 100,000 western lowland gorill ...

Eastern Gorilla
The eastern gorilla (''Gorilla beringei'') is a critically endangered species of the genus ''Gorilla'' and the largest living primate. At present, the species is subdivided into two subspecies. There are 6,800 eastern lowland gorillas or Grauer's gorillas (''G. b. graueri'') and 1,000 mountain gorillas (''G. b. beringei''). Illegal hunting threatens the species. Taxonomy and phylogeny There are two recognised subspecies of eastern gorilla: the mountain gorilla (''Gorilla beringei beringei'') of the volcanic slopes of Rwanda, Uganda and eastern Democratic Republic of Congo; and the eastern lowland gorilla or Grauer's gorilla (''Gorilla beringei graueri'') in eastern Democratic Republic of Congo. The eastern lowland gorillas and mountain gorillas were previously thought to be two of the three subspecies of one single species, the gorilla (''Gorilla gorilla''). However, genetic research has shown that the two eastern subspecies are far more closely related than the western ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Ape
The Hominidae (), whose members are known as the great apes or hominids (), are a taxonomic family of primates that includes eight extant species in four genera: '' Pongo'' (the Bornean, Sumatran and Tapanuli orangutan); '' Gorilla'' (the eastern and western gorilla); '' Pan'' (the chimpanzee and the bonobo); and ''Homo'', of which only modern humans (''Homo sapiens'') remain. Numerous revisions in classifying the great apes have caused the use of the term ''hominid'' to change over time. The original meaning of "hominid" referred only to humans (''Homo'') and their closest extinct relatives. However, by the 1990s humans and other apes were considered to be "hominids". The earlier restrictive meaning has now been largely assumed by the term ''hominin'', which comprises all members of the human clade after the split from the chimpanzees (''Pan''). The current meaning of "hominid" includes all the great apes including humans. Usage still varies, however, and some scientis ...

Human Evolutionary Genetics
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological, medical, historical and forensic implications and applications. Genetic data can provide important insights into human evolution. Origin of apes Biologists classify humans, along with only a few other species, as great apes (species in the Family (biology), family Hominidae). The living Hominidae include two distinct species of Pan (genus), chimpanzee (the bonobo, ''Pan paniscus'', and the chimpanzee, ''Pan troglodytes''), two species of gorilla (the western gorilla, ''Gorilla gorilla'', and the eastern gorilla, ''Gorilla graueri''), and two species of orangutan (the Bornean orangutan, ''Pongo pygmaeus'', and the Sumatran orangutan, ''Pongo abelii''). The great apes with the family Hylobatidae of gibbons form the superfamily Hominoidea of apes. Apes, in turn, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanno The Navigator
Hanno the Navigator (sometimes "Hannon"; , ; ) was a Ancient Carthage, Carthaginian explorer (sometimes identified as a king) who lived during the 5th century BC, fifth century BC, known for his Navy, naval expedition along the coast of West Africa. However, the only source of said voyage is a ''periplus'' translated into Greek. Historians have attempted to identify specific locations along Hanno's route, based on the ''periplus''. According to some modern analyses, his expedition could have potentially reached as far south as Gabon; still, according to other sources, he could not have sailed much farther than coastal southern Morocco. Biography The name of Hanno was given to many Carthaginians. Ancient texts which specifically mention Hanno the Navigator do not provide much in the way of positively identifying him; some authors referred to him as a king, while others referred to him with the Latin words ''wikt:dux#Latin, dux'' (leader, general) or ''wikt:imperator#Latin, i ...

Primate
Primates is an order (biology), order of mammals, which is further divided into the Strepsirrhini, strepsirrhines, which include lemurs, galagos, and Lorisidae, lorisids; and the Haplorhini, haplorhines, which include Tarsiiformes, tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial animal, terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among Canopy (biology), tree tops, including large brain sizes, binocular vision, color vision, Animal communication, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (in most but not all) that enable better grasping and dexterity. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is ...
