For snakes and lizards, the best way to distinguish them is whether they have limbs or not, but some lizards have slowly evolved to snakes, such as snake lizards, snake lizard limbs have been completely degraded, and some lizard limbs are slowly degenerating, such as the limbs of three-toed lizards have become smaller and smaller, is this evolutionary or degenerate for lizards?
The English name of the three-toed lizard is Western Three-toed Skink, which translates as: Western three-toed lizard, three-toed stone dragon, etc., they are mainly distributed in Europe, is a common stone dragon in Europe, and is most common in Italy, France, Spain and Portugal in Europe.
Three-toed lizards have become less and less like a lizard, their limbs have degenerated to the point of being almost invisible, but they are not snakes after all, they obviously have legs under close inspection, and in terms of classification, they belong to the subfamily Officinalis, and their true identity is still a lizard.
According to scientists: the legs of the three-toed lizard continue to degenerate! Is the three-toed lizard really going to completely degenerate into a snake? The reason why the limbs will slowly disappear is related to the habitat of the three-toed lizard, the three-toed lizard generally inhabits under the stones or in the grass, and the snake-like movement mode is better for them, so the limbs become a burden in evolution, becoming smaller and smaller, the limbs slowly disappear, and eventually may evolve into a "snake lizard"!
The limbs of the three-toed lizard are degrading in order to better adapt to the environment, but even without the limbs, they are still different from snakes: lizards do not have a forked tongue, can not scare off enemies like snakes spit out snake letters, snakes cannot "break their tails to survive", but three-toed lizards can break their tails, and later they can grow new tails, and the breeding methods of three-toed lizards are similar to those of other species of the plesiosaur family!
The limbs of the three-toed lizard slowly disappeared, did it degenerate into a snake, or did it evolve into a snake? In nature, snakes are more aggressive than lizards, and perhaps this lizard wants to degenerate its limbs and disguise itself as a snake, get better living conditions, and adapt to the laws of nature!
Pay attention to the six dimensions of nature And let nature know nature!
