A mammal breathes air and has a backbone. (or if you want to be all sciency you can say that they are "vertebrates")
Hope this helped! I edited it from the last one which was most unhelpful! :)
Mammals are defined as vertebrate chordates that have hair and suckle their young, have more than 1 type of tooth and a flap on the ear that may be called a pinna. The classification is as follows: Domain Eukarya; living organisms with nuclei to contain the DNA in all cells but red blood cells Kingdom Animalia; multicellular, nonphotosynthetic organisms with nucleated cells Phylum Chordata; animals with a rod down their backs at some time of development called a notochord Subphylum Vertebrata; chordates with a true backbone Class Mammalia; as defined above there are 21 orders of mammals and 4500 species approximately
There are many subclassifications of mammals. However, the four characteristics that define a mammal are having hair, mammary glands, three middle ear bones, and the neocortex region of the brain.
Young are born alive, and not hatched from eggs, and young are nursed with milk produced by their mother.
