Transitions Of Reptiles To Mammals

Transition from reptiles to mammals long ago, among the less distant galaxies there was a blue planet called Earth, and there were no mammals living in this world. However, many hours have passed since then, and we currently have many furry creatures collectively known as mammals. How did they get them? Where is it? These are questions that lead me to choose a theme. I will try to provide some examples of specific transition fossil uses to show that mammals have evolved from a group of reptiles and are not placed here by unknown forces.

For countless generations, the transition from reptiles to mammals is a gradual process that often involves a slow accumulation of long-term mammalian features. These include, for example, smaller body shapes, larger cerebral cavities, and middle ears with three bones. The latter greatly improved many new types of hearing at that time. Then another new feature will appear in the space behind the I socket and will provide more brain material and additional space for the larger jaw. This creates new jaw hinges and increasingly complex teeth

Transient fossils between the groups were discovered. One of the most impressive transition series is an ancient reptile of modern mammalian migration. Bone details in mammals and reptiles differ, especially in the skull. Reptile jaw has four bones. The most important thing is called volunteer. In mammals, the mandible is the only bone in the mandible. The other bones are part of the middle ear. Reptile jaws are fragile and have undifferentiated teeth. Their jaws are closed by three muscles: lateral, posterior and internal adductor muscles. Each reptile's teeth is one. Mammals have strong jaws and teeth. Many of these teeth such as tooth decay are fangs. The diaphragm and masseter muscles from the adductor muscle are near the chin of the mammal. As mammals have secondary tendons to separate the nostrils from the throat, most people can swallow or breathe at the same time. Reptiles lack this

When mammals evolved from a series of reptiles, the evolution of life has undergone a major change. This transformation began when the reptiles, including Dimetrodon, produced the devastation of "beasts" in the Permits (286-248 million years ago). (Another big branch, "Lizard's face" lizard has birds and modern reptiles). These mammalian-like reptiles similarly produced similar analogs. Trinaxoidone in the Triassician This line provides a series of quality transition fossils. The development of important mammalian traits can be traced back to the fossil history of this group. There are only a single bone in the mandible (compared to some of the lower reptiles). At the top there are excellent transitional fossils with jaws and reptile and mammalian joints, Diarthrognathus and Morganucodon.
