Mammals have few similarities to amphibians as compared to the number of differences between them. However, some similarities include:
1. Both, as adults, breathe oxygen.
2. Both have spines and endoskeletons.
3. Both have bilateral symmetry.
4. Both have many internal organs in common, such as bones, muscles, brains, hearts, lungs, kidneys, bladders*, livers, tracheae, gall bladders, esophagi, stomachs, and intestines.
5. Both are tetrapods, but some species of both classes (e g whales, caecilians) have lost some of their limbs.
*The bladders of amphibians are usually not connected to the urinary ducts. They are in a pocket in the cloaca.

Are human beings related to reptiles?
Ultimately all organisms are related. Humans are mammals, which are not closely related to reptiles. Mammals and reptiles belong to a group of animals called amniotes, which they also share with birds. Amniotes include all land vertebrates except amphibians. The last common ancestor of mammals and reptiles lived over 300 million years ago in the Carboniferous period. Shortly after the first amniotes branched off from amphibians they split into synapsids, which became the ancestors of mammals, and sauropsids, which became the ancestors of birds and all modern reptiles.
