Orycteropodidae
Orycteropodidae is a family of afrotherian mammals. Although there are many fossil species, the only species surviving today is the aardvark, ''Orycteropus afer''. Orycteropodidae is recognized as the only family within the order Tubulidentata, from the Latin words ''tubulis'' (tubule) and ''dentis'' (tooth), referring to the tubule-style teeth., so the two are effectively synonyms. Evolution The first aardvark fossil discovered was originally named ''Orycteropus gaudryi'' (now '' Amphiorycteropus'') and was found in Turolian deposits on the island of Samos. Since then, representatives of the order Tubulidentata have been located from the Oligocene in what is now Europe, and it is believed that the order probably originated around 65–70 million years ago or in the Paleocene. They are thought to be closely related to the now extinct Ptolemaiida, a lineage of carnivorous afrotheres. The family arose in Africa in the Early Miocene epoch, and spread to Eurasia later in the Miocen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aardvark
Aardvarks ( ; ''Orycteropus afer'') are medium-sized, burrowing, nocturnal mammals native to Africa. Aardvarks are the only living species of the family Orycteropodidae and the order Tubulidentata. They have a long proboscis, similar to a pig's snout, which is used to sniff out food. They are afrotheres, a clade that also includes elephants, manatees, and hyraxes. They are found over much of the southern two-thirds of the African continent, avoiding areas that are mainly rocky. Nocturnal feeders, aardvarks subsist on ants and termites by using their sharp claws and powerful legs to dig the insects out of their hills. Aardvarks also dig to create burrows in which to live and rear their young. Name and taxonomy Name The aardvark is sometimes colloquially called the "African ant bear", "anteater" (not to be confused with the South American anteaters), or the "Cape anteater" after the Cape of Good Hope. The name "aardvark" is Afrikaans () and comes from earlier Afrikaa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammal Genera
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families. The taxonomy represented here is a compilation of the most logical and up-to-date information on mammalian taxonomy from many sources, the main ones being '' Handbook of the Mammals of the World'' series and '' Mammal Species of the World''.

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (; 15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Louis-Jean-Marie Daubenton at the College de France and Fourcroy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
