Milk is produced in the mammary glands, and it is from here mammals have gotten their name.2. The lower jaw in mammals is a single bone on either side. In all other vertebrates there are more than one bone on each side of the jaw3.The mammal middle ear, and only the mammal middle ear, contains 3 bones. The Stapes or (Stirrup), Incus or (Anvil) and the Malleus or (Hammer)4.In mammals the main artery leaving the heart curves to the left becoming the aortic arch. In birds it curves to the right and in all other vertebrates there are more than one main artery leaving the heart.5.Mammals have a diaphragm. A sheet of muscle and tendon that separates the body cavity into two sections. Heart and lungs before/above, liver, kidneys, stomach, intestines, etc, behind/below. No other animal has a diaphragm.6.No other animal has hair in the same form as mammals, and all mammals have some hair at least at the beginning of their lives - baby whales and dolphins are born with a moustache.And then there are several more than mammals share with other groups, like verterbrae and that mammals are warm blooded, and that mammals have lungs to breathe airAll mammals are warm blooded,All mammals are air breathersMammals give live birthEvery mammal is a vertebrate.
