What are the differences between synappers and sauropsids?

Synapsides include mammals and our distant ancestors, including pelycosaurs and therapsid, while sauropsid is another word for reptiles. Synapside means "fused arch", reference to the structure of the skull. Another name for synapside is Theropsid , which means "Beast Face", unlike sauropsid , which means "lizard". Synapsides are sauropsids are two evolutionary amniot lines that include all non -lamps of tetrapods and their descendants (such as whales that come from tetraples, but lost their legs when they became exclusively naval). Soon the synappers were called "mow reptiles", but this is an incorrect watch, because they were not reptiles at all. They both looked like small lizards. At that time, there were tetraps in water for about 45 million years and on Earth for at least 20 million years. BOTH are amniotic, these are animals with complex eggs that can be laid on the ground, unlike amphibians that have to lay eggs in the water. Before Synapsides and Sauropsids were divided, exSome of the amnote of the tribal groups that did not fit into any group. Amniots were destined to inherit the Earth because they are the only ground vertebrates who can dare significant distances from the water and still survive.

The difference between sauropsides and synappers is defined in terms of holes in their skull. Synapsides have another hole used to reduce the weight of the skull and provide the point of attachment for the jaw muscles. Sauropsids began without holes in the skull, then developed one pair, with each hole behind the eyes. Initially, both groups were "cold -blooded" (ectotermic).

From the late carbon, the colonization of the country by large creatures was evolutionary arms racemezi synapses and sauropsids. Synapsides have come to a great start, diversified faster than sauropsides, and gave the emergence of most large animals permian, including successful pelycosaurs, some of which were as large as cargo AUTomobils and had only the only predators of the peak of that time.

At the end of the Permium, the greatest synappers were extinct, so many niches were open for exploitation. They used the Sauropsids, eventually triggered dinosaurs who dominated Earth throughout the Mesozoice. About 65 million years ago, the tables turned again when the asteroid erased all the non -Non -Nemian dinosaurs. Synapsids again ruled the world in the form of mammals. Synapsids eventually triggered people, probably the most evolutionarily more successful terrestrial vertebrates in the history of life on Earth.
