The amniotic egg is the key characteristic of amniotes. Animals are divided into different phyla on the basis of: Which of the following is not an advantage of a body cavity? Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water. The evolution of amniotic membranes meant that the embryos of amniotes were provided with their own aquatic environment, which led to less dependence on water for development and thus allowed the amniotes to branch out into drier environments. For many years, the wild Bactrian was thought to be a subspecies of the domestic Bactrian. These differences are reflected in the heart, lungs, and kidneys mainly. One of the camel's noises was even used to voice the character Chewbacca in the Star Wars movies. Sauropsids include turtles, lizards, crocodiles, and birds.

They are warm-blooded vertebrates more related to reptiles than to mammals. Reptile parents provide little if any care to their young. Formally, this constitutes many different groups, but the sauropsid amniotes share many derived characteristics which separate them from the synapsids. Thealbumin, or egg white, outside of the chorion provides the embryo with water and protein, whereas the fattier egg yolk contained in the yolk sac provides nutrients for the embryo, as is the case with the eggs of many other animals, such as amphibians.

There are two main divisions of amniotes, the sauropsid amniotes and the synapsid amniotes. This birthing shift from land to water cultivated other differences that made reptiles suitable for terrestrial instead of aquatic life. Most camels tower above humans. Reduce competition for pools of water in which larvae can mature. This earned these beasts of burden a nickname, "ships of the desert."
