Hello guys, welcome to my post, In this post i'll tell you how snakes lost their leg these informations are based on scientists research
So you don't need to doubt on this, be fully confirmed.

All living creatures in our surroundings have feet, except snakes, but snakes can run easily without foot. Often people think that what can be the reason that snakes do not have legs. So science has found the answer.

Scientists have found 9 million years old remains of snakes. Through this remnant he has received many important information. Scientists scanned the snake's residue and the CT of the present's snake found that their ancestors responsible for not having feet.
Because this relic has shown that the first snake used to have legs too. According to Hongyu Yi, chief researcher at Edinburgh University, the reason for losing the snake's legs is to be their bills. Because of being in the bill, he got used to crawling in and he gradually gave up the use of the feet.

He said on the basis of estimate that the reason for this may be that generations of generations have lost their feet. Even with the legs of a snake, he used to crawl his legs and snatched them from them. For this reason the scientists have described the ancestors of snakes as responsible for not having their feet. If he used to keep legs, then today the snake is also legged.
