Cornelius Van Der Horst
Cornelius Jan van der Horst (11 May 1889, Nieuwer-Amstel – 10 October 1951, Johannesburg) was a Dutch biologist who worked mainly on marine biology and embryology in both the Netherlands and South Africa. As an undergraduate he studied botany and zoology at the University of Amsterdam where he was appointed assistant in the Botany Department under Professor Dr Hugo de Vries before moving on to assist Max Wilhelm Carl Weber at the University's Zoological Museum and in 1917 he became the principal assistant for general Zoology. In 1916 he published his thesis ''De motorische kernen en banen in de hersenen der visschen. Hare taxonomische waarde en neurobiotactische beteekenis'' ("The motor nuclei and orbits in the brain of the fish. Its taxonomic value and neurobiotactic meaning "). The research for this thesis was carried out at the Netherlands Central Institute for Brain Research under C. U. Ariëns Kappers. In 1925 Van der Horst was appointed Deputy Director of this Netherl ...

Nieuwer-Amstel
Amstelveen () is a municipality in the province of North Holland, Netherlands with a population of 92.353 as of 2022. It is a suburban part of the Amsterdam metropolitan area. The municipality of Amstelveen consists of the historical villages of Bovenkerk and Nes aan de Amstel. In addition, as well as Downtown Amstelveen (Dutch: ''Amstelveen stadshart''), the following neighbourhoods have been recently built: Westwijk, Bankras-Kostverloren, Groenelaan, Waardhuizen, Middenhoven, Randwijk, Elsrijk and Keizer Karelpark. The name comes from the Amstel, a local river (as does the name Amsterdam) and , meaning fen, peat, or moor. Amstelveen houses the international headquarters of Dutch national airline KLM (although it is slated to leave for Schiphol in 2024) and KPMG, one of the Big Four accounting firms. The Cobra Museum is also located in Amstelveen. History During the French occupation between 1810 and 1814, Amstelveen was the capital of a canton in the French department Zu ...

Linnean Society
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Aardvark
The aardvark ( ; ''Orycteropus afer'') is a medium-sized, burrowing, nocturnal mammal native to Africa. It is the only living species of the order Tubulidentata, although other prehistoric species and genera of Tubulidentata are known. Unlike most other insectivores, it has a long pig-like snout, which is used to sniff out food. It roams over most of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. A nocturnal feeder, it subsists on ants and termites, which it will dig out of their hills using its sharp claws and powerful legs. It also digs to create burrows in which to live and rear its young. The animal is listed as "least concern" by the IUCN, although its numbers are decreasing. Aardvarks are afrotheres, a clade which also includes elephants, manatees, and hyraxes. Name and taxonomy Name The aardvark is sometimes colloquially called the "African ant bear", "anteater" (not to be confused with the anteater, South American anteater), ...

Afrotheria
Afrotheria ( from Latin ''Afro-'' "of Africa" + ''theria'' "wild beast") is a clade of mammals, the living members of which belong to groups that are either currently living in Africa or of African origin: golden moles, elephant shrews (also known as sengis), tenrecs, aardvarks, hyraxes, elephants, sea cows, and several extinct clades. Most groups of afrotheres share little or no superficial resemblance, and their similarities have only become known in recent times because of genetics and molecular studies. Many afrothere groups are found mostly or exclusively in Africa, reflecting the fact that Africa was an island continent from the Cretaceous until the early Miocene around 20 million years ago, when Afro-Arabia collided with Eurasia. Because Africa was isolated by water, Laurasian groups of mammals such as insectivores, rodents, lagomorphs, carnivorans and ungulates could not reach Africa for much of the early to mid-Cenozoic. Instead, the niches occupied by those groups on the ...

Heinrich Georg Bronn
Heinrich Georg Bronn (3 March 1800 – 5 July 1862) was a German geologist and paleontologist. He was the first to translate Charles Darwin's ''On the Origin of Species'' into German in 1860, although not without introducing his own interpretations, as also a chapter critiquing the work. Bibliography Bronn was born at Ziegelhausen (now part of Heidelberg) in the electoral Palatinate. Studying at the university of Heidelberg he took his doctor's degree in the faculty of medicine in 1821, and in the following year was appointed professor of natural history. He now devoted himself to palaeontological studies, and to field-work in various parts of Germany, Italy and France. From its commencement in 1830 to 1862 he assisted in editing the ''Jahrbuch für Mineralogie'' continued as ''Neues Jahrbuch''. His principal work, ''Letkaea Geognostica'' (2 vols., Stuttgart, 1834–1838; 3rd ed. with F. Romer, 3 vols., 1851–1856), has been regarded as one of the foundations of German strati ...

Neoceratodus
''Neoceratodus'' is a genus of lungfish in the family Neoceratodontidae. The extant Australian lungfish (''Neoceratodus forsteri'') is the only surviving member of this genus, but it was formerly much more widespread, being distributed throughout Africa, Australia, and South America. Species were also much more diverse in body plan; for example, the Cretaceous species '' Neoceratodus africanus'' was a gigantic species that coexisted with ''Spinosaurus'' in what is now the Kem Kem Formation of Morocco. The earliest fossils from this genus are of ''Neoceratodus potkooroki'' from the mid Cretaceous (Albian-Cenomanian) Griman Creek Formation of Australia, remains from the Late Jurassic of Uruguay assigned to this genus probably do not belong to the genus. Species The following species are currently classified in this genus: * †'' Neoceratodus africanus'' * †'' Neoceratodus eyrensis'' * ''Neoceratodus forsteri'' (Queensland lungfish) *†'' Neoceratodus potkooroki'' * †'' Neo ...

Nils Holmgren
Nils Frithiof Holmgren (1877–1954) was a Swedish zoologist and comparative anatomist. He was professor of zoology at Stockholm University from 1921 to 1944. In 1906 Holmgren defended his doctoral dissertation at Stockholm University. In 1912 he became a teacher there, and in 1919 assistant professor of zoology, and in 1921 full professor. His early work focussed on the biology, systematics and anatomy of insects, especially termites, as in (1906) and (1909–1912). In later work he focused on the structure of the brain in worms, arthropods and vertebrates, publishing (1916) (Comparative anatomy of the brain), (1919), (1920), ''Points of view concerning forebrain morphology in lower vertebrates'' (1922), (with C. J. van der Horst) ''Contribution to the morphology of the brain'' in Ceratodus (1925), and ''Points of view concerning forebrain morphology in higher vertebrates'' (1925). This work made him a world expert on the nervous systems of the lower vertebrates. Later w ...

Elacatinus Horsti
''Elacatinus horsti'', the yellowline goby, is a species of goby native to the western Atlantic Ocean and the Caribbean Sea. Description The yellowline goby grows to be in length. It has a rounded snout and a long, slim body. The upper parts are black and the underside is grey, gradually paling to white. Some fish have a bright, yellow stripes running along each side from the eye to the tail, with often a yellow spot or short line on the snout. In juvenile fish, this stripe is shorter and extends just beyond the base of the pectoral fin. Young '' Elacatinus chancei'' is very similar in appearance, but in that species, the yellow line hardly reaches the pectoral fin. In another form of the fish, the stripe is white, paling to a bluish-grey colour beyond the pectoral fin. The dorsal fin is in two parts, and has seven spines and 11 to 12 soft rays.
