Evolution of Defensive Mechanisms in Reptiles

Reptiles, reptiles are evolution levels of eukaryotes including today's turtles, crocodiles, snakes, lizards, and many other threatened groups. Reptiles are on the planet millions of years ago and have undergone a myriad of mutations. One area of ​​concern is how these living things defend their predators' evolution. Over time, evolution has led to the development of various defense mechanisms, including many camouflage, venom, armor, armor, behavior and other abnormal forms, with many reptilian subspecies.

Defensive Features: Both reptiles and amphibians use camouflage, biting and bulging to avoid predation. Both lizards (reptiles) and crickets (amphibians) have the ability to automatically disconnect, this is the spontaneous removal of the tail as a defense reaction. General defense is fake, and congenital defenseless animals protect the vivid colors of dangerous animals. For example, a harmless king snake might look like a poisonous coral snake. Warning: This is when the reptile warns potential predators by smelling, or when they shake their tails like rattlesnakes. Some horned lizards (Phrynosoma) can smell blood from their eyes to protect them from predators. The distribution of blood is called automatic bleeding of eyes. If the warning fails, some reptiles begin to attack.

Why are we fighting? You will think that thousands of years of evolution preclude this bad feature. One theory is that when coming back on that day, snoring is defense against predators - it is easier to wake up from sleeping when snoring, and warns every animal of potentially dangerous people by noise It is that.

When mammals evolved from a series of reptiles, the evolution of life has undergone a major change. This change began when the reptiles, including Dimetrodon, produced 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 is an excellent transient fossil with jaws and reptile and mammalian joints, Diarthrognathus and Morganucodon.
