Monkey
Monkeys are haplorhine primates, a group generally possessing tails and consisting of about 260 known living species. Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons. Most species are also active during the day (diurnal). Monkeys are generally considered to be intelligent, particularly Old World monkeys. There are two major types of monkey: New World monkeys (platyrrhines) from South and Central America and Old World monkeys (catarrhines of the superfamily Cercopithecoidea) from Africa and Asia. Hominoid apes (consisting of gibbons, orangutans, gorillas, chimpanzees, and humans), which all lack tails, are also catarrhines but are not considered monkeys, although often they or their ancestors are (which cladistically automatically implies homonoids are as well.)
Primate
A primate ( ) is a mammal of the order Primates (Latin: "prime, first rank"). In taxonomy, primates include two distinct lineages, strepsirrhines and haplorhines. Primates arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. Most primate species remain at least partly arboreal. With the exception of humans, who inhabit every continent, most primates live in tropical or subtropical regions of the Americas, Africa and Asia. They range in typical size from Madame Berthe's mouse lemur, which weighs only , to the eastern gorilla, weighing over .
Subfossil lemur
Subfossil lemurs are lemurs from Madagascar that are represented by recent (subfossil) remains dating from nearly 26,000 years ago (from the late Pleistocene until the Holocene) to approximately 560 years ago. They include both living and extinct species, although the term more frequently refers to the extinct giant lemurs. The diversity of subfossil lemur communities was greater than that of present-day lemur communities, ranging from as high as 20 or more species per location, compared with 10 to 12 species today. Extinct species are estimated to have ranged in size from slightly over to roughly .
Lemur
Lemurs ( ) are a clade of strepsirrhine primates endemic to the island of Madagascar. The word "lemur" derives from the word "lemures" (ghosts or spirits) from Roman mythology and was first used to describe a slender loris due to its nocturnal habits and slow pace, but was later applied to the primates on Madagascar. As with other strepsirrhine primates, such as lorises, pottos, and galagos (bush babies), lemurs share resemblance with basal primates. In this regard, lemurs are often confused with ancestral primates, when in actuality, lemurs did not give rise to monkeys and apes, but evolved independently.
Strepsirrhini
Strepsirrhini or Strepsirhini (; ) is a suborder of primates that includes the lemuriform primates, which consist of the lemurs of Madagascar, galagos ("bushbabies") and pottos from Africa, and the lorises from India and southeast Asia. Collectively they are referred to as strepsirrhines. Also belonging to the suborder are the extinct adapiform primates, a diverse and widespread group that thrived during the Eocene (56 to 34 million years ago [mya]) in Europe, North America, and Asia, but disappeared from most of the Northern Hemisphere as the climate cooled; the last of the adapiforms died out at the end of the Miocene (~7 mya).
Animal testing on non-human primates
Experiments involving non-human primates (NHPs) include toxicity testing for medical and non-medical substances; studies of infectious disease, such as HIV and hepatitis; neurological studies; behavior and cognition; reproduction; genetics; and xenotransplantation. Around 65,000 NHPs are used every year in the United States, and around 7,000 across the European Union. Most are purpose-bred, while some are caught in the wild. Their use is controversial. According to the Nuffield Council on Bioethics, NHPs are used because their brains share structural and functional features with human brains, but "[w]hile this similarity has scientific advantages, it poses some difficult ethical problems, because of an increased likelihood that primates experience pain and suffering in ways that are similar to humans."
Crowned eagle
The crowned eagle, also known as the African crowned eagle or the crowned hawk-eagle ("Stephanoaetus coronatus") is a large bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to eastern areas. Its preferred habitats are principally riparian woodlands and various forests. The crowned eagle is the only extant member of the genus "Stephanoaetus". A second species, the Malagasy crowned eagle ("Stephanoaetus mahery") became extinct after humans settled on Madagascar. At least 90 per cent of the diet is mammalian; the usual prey taken by populations shows pronounced regional differences.
