Taxonomically, Reptilia and Synapsida (a group of mammal-like reptiles and their extinct family members) had been sister groups that diverged from a standard ancestor through the Middle Pennsylvanian Epoch . For hundreds of thousands of years representatives of these two teams have been superficially comparable. However, slowly life diverged, and from the synapsid line got here hairy mammals that possessed an endothermic (heat-blooded) physiology and mammary glands for feeding their young. All birds and a few groups of extinct reptiles, similar to chosen teams of dinosaurs, additionally evolved an endothermic physiology. However, the majority of fashionable reptiles possess an ectothermic (chilly-blooded) physiology. Today solely the leatherback sea turtle has a near-endothermic physiology. So far no reptile, living or extinct, has developed specialized pores and skin glands for feeding its young.
Goodrich supported this division by the nature of the hearts and blood vessels in each group, and other features, such as the structure of the forebrain. According to Goodrich, both lineages advanced from an earlier stem group, Protosauria (“first lizards”) during which he included some animals right now thought-about reptile-like amphibians, in addition to early reptiles. Reptiles are tetrapod vertebrates, creatures that both have four limbs or, like snakes, are descended from four-limbed ancestors. Unlike amphibians, reptiles wouldn’t have an aquatic larval stage. As amniotes, reptile eggs are surrounded by membranes for protection and transport, which adapt them to replica on dry land. Many of the viviparous species feed their fetuses … Read More
