Taxonomically, Reptilia and Synapsida (a group of mammal-like reptiles and their extinct relatives) had been sister groups that diverged from a standard ancestor during the Middle Pennsylvanian Epoch . For hundreds of thousands of years representatives of these two teams had been superficially comparable. However, slowly life diverged, and from the synapsid line got here bushy mammals that possessed an endothermic (heat-blooded) physiology and mammary glands for feeding their young. All birds and a few teams of extinct reptiles, such as selected groups of dinosaurs, additionally advanced an endothermic physiology. However, the vast majority of fashionable reptiles possess an ectothermic (chilly-blooded) physiology. Today only the leatherback sea turtle has a close to-endothermic physiology. So far no reptile, living or extinct, has developed specialised pores and skin glands for feeding its young.
