Concept explainers
To explain: The amniotes that are endothermic.
Concept introduction: In the late Devonian era, the aquatic vertebrates are adapted to terrestrial vertebrates. This is the most important adaptation in the terrestrial life to complete their life cycles on land habitat. The amniotic egg mainly contains an amnion. Amnion is a membrane that forms an embryonic sac around the embryo. The terrestrial vertebrates are known as amniotes due to the presence of amnion around the embryo.
To describe: The advantages of endothermy.
