Afrotheria (/ æ f r oʊ ˈ θ ɪər i ə / from Latin Afro-"of Africa" + theria "wild beast") is a superorder 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), otter shrews, tenrecs, aardvarks, hyraxes, elephants, sea cows, and several extinct clades.
Mar 14, 2022 · They are each other’s closest living relatives, and all belong to the placental mammal clade Afrotheria (‘African beasts’), which is one of the four major clades of placental mammals along with Xenarthra (anteaters, sloths, armadillos), Euarchontoglires (e.g. rodents, rabbits, primates), and Laurasiatheria (e.g. bats, carnivorans, odd ...
The Afrotheria Specialist Group deals with very few species — there is only one aardvark, 6 hyraxes, 19 sengis, 21 golden moles, and 34 tenrecs. Many of these species have broad distributions in a wide variety of habitats, which means they are not particularly vulnerable to extinction (the aardvark, for example, and several hyraxes and sengis).
Jan 2, 2001 · Afrotheria: Plate tectonics meets genomics. Afrotheria is one of the most remarkable hypotheses in mammal evolution. It suggests that one-third of the orders of placental mammals form an ancient group that evolved on Africa when that continent was isolated from others through plate tectonics ( 1 ). Although this hypothesis has been predicted by ...

Mar 25, 2008 · The supraordinal mammalian clade Afrotheria was first recognized in its entirety based on DNA analysis dating to the mid-1990s. Since then, this “African clade”, which includes proboscideans, sirenians, hyracoids, tubulidentates, elephant-shrews, tenrecs and chrysochlorids, has been supported by numerous molecular and genomic studies. According to these molecular inferences, the origin of ...
