[1] Mammalogy has also been known as " mastology ", " theriology ", and " therology ". The archive of number of mammals on earth is constantly growing ...
Primates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers and simians (monkeys and apes). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted for life in tropical forests: many primate ...
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of the defining features of marsupials is their unique reproductive strategy, where the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's ...
Cetartiodactyla is a large order of hoofed mammals, the even-toed ungulates, and aquatic mammals, cetaceans. Cetacea was found to be nested within "Artiodactlya" and has now been moved into that order, whose name is now Cetartiodactyla. [2] Even-toed ungulates are found nearly world-wide, although no species are native to Australia or Antarctica.
