Douglas Harper's Etymology Dictionary

1826, anglicized form of Modern Latin Mammalia (1773), coined 1758 by Linnaeus for the class of mammals, from neuter Late Latin mammalis "of the breast," from Latin mamma "breast," perhaps cognate with mamma.


n. 1 An animal of the class Mammalia, characterized by being warm-blooded, having hair and feeding milk to its young. 2 (context paleontology English) A vertebrate with three bones in the inner ear and one in the jaw.


n. any warm-blooded vertebrate having the skin more or less covered with hair; young are born alive except for the small subclass of monotremes and nourished with milk


Mammals ( class Mammalia from Latin mamma "breast") are a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands.

Mammals include the largest animals on the planet, the great whales, as well as some of the most intelligent, such as elephants, primates and cetaceans. The basic body type is a terrestrial quadruped, but some mammals are adapted for life at sea, in the air, in trees, underground or on two legs. The largest group of mammals, the placentals, have a placenta, which enables the feeding of the fetus during gestation.

Mammals range in size from the bumblebee bat to the blue whale. With the exception of the five species of monotreme (egg-laying mammals), all modern mammals give birth to live young. Most mammals, including the six most species-rich orders, belong to the placental group. The three largest orders in number of species are Rodentia: mice, rats, porcupines, beavers, capybaras and other gnawing mammals; Chiroptera: bats; and Soricomorpha: shrews, moles and solenodons. The next three biggest orders, depending on the biological classification scheme used, are the Primates including the great apes and monkeys; the Cetartiodactyla including whales and even-toed ungulates; and the Carnivora which includes cats, dogs, weasels, bears and seals.

The word " mammal" is modern, from the scientific name Mammalia, coined by Carl Linnaeus in 1758, derived from the Latin mamma ("teat, pap"). All female mammals nurse their young with milk, which is secreted from special glands, the mammary glands. According to Mammal Species of the World, 5,416 species were known in 2006. These were grouped in 1,229 genera, 153 families and 29 orders. In 2008 the International Union for Conservation of Nature (IUCN) completed a five-year, 1,700-scientist Global Mammal Assessment for its IUCN Red List, which counted 5,488 species. In some classifications, extant mammals are divided into two subclasses: the Prototheria, that is, the order Monotremata; and the Theria, or the infraclasses Metatheria and Eutheria. The marsupials constitute the crown group of the Metatheria, and include all living metatherians as well as many extinct ones; the placentals are the crown group of the Eutheria. While mammal classification at the family level has been relatively stable, several contending classifications regarding the higher levels—subclass, infraclass and order, especially of the marsupials—appear in contemporaneous literature. Much of the changes reflect the advances of cladistic analysis and molecular genetics. Findings from molecular genetics, for example, have prompted adopting new groups, such as the Afrotheria, and abandoning traditional groups, such as the Insectivora.

The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsids—sometimes referred to as mammal-like reptiles—before giving rise to the proto-mammals ( Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of non-avian dinosaurs, and have been among the dominant terrestrial animal groups from 66 million years ago to the present.

Mammal (EP)

Mammal is the self-titled debut Extended play (EP), by Australian hard rock band, Mammal from 2006. The band sold the EP independently at their live shows and on their website until early 2007 when they signed with Metropolitan Groove Merchants (MGM) to distribute it independently. The original version (no longer in print) was replaced by the MGM version, released in March. The EP peaked into the top 20 of the AIR Charts.

Mammal (band)

Mammal were an Australian band that formed in March 2006. Mammal rose up the ranks of the Australian music scene very quickly. Their first self-titled EP was recorded soon after the band came together. Their debut live album "Vol:1 The Aural Underground" was recorded just 4 months after the band started touring at a sold out show at The Evelyn Hotel on 2 February 2007. Mammal also released a single titled "Slaves/Nagasaki in Flames" AA side, featuring 3 songs. Mammal entered the studio on 21 April 2008 to begin recording their debut studio album, The Majority which was released in August 2008. It peaked at No. 51 on the ARIA Albums Chart in early September. Some of the band's songs, including Hell Yeah!, New Breed Judas and Slaves, received regular airplay on Australian radio station Triple J.
