Mammal. Mammals are the class of vertebrate animals characterized by the presence of hair (or fur) and mammary glands, which in females produce milk for the nourishment of young. The other extant (living) classes of vertebrates (animals with backbones) include fish (with a few recognized classes), amphibians, reptiles, and birds .
Mammals became the dominant land animals after non-bird dinosaurs were eliminated. Recent work helped to explain their success: epigenetics seems to have started in early mammals. Mammals are in the class Mammalia. They are a group of vertebrate animals. They have fur or hair and very precise temperature regulation.
Caractéristiques. Les mammifères sont d'abord caractérisés – comme leur nom le rappelle – par l' allaitement. Les mammifères forment une classe d'animaux vertébrés descendant des Thérapsides .
