ORGIN OF SNAKE
Snake is a family tree of Reptails all reptails will move slowly and it can survive in both water and land but snake hos no leg now but 150 Million years ago the snakes which had a legs and it used leg to survive .
The above image is decayed snake bone research says around 150M years before all the snakes lived with leg by due to earth evolution it lost its legs and survived in the land without leg and it try to move in zig-zag manner to move one place to another . Snakes are reptiles with no legs. They move by using their muscles to push their scales against the ground or other objects.
HOW SNAKE LOST
How it lost? , we didn’t get clear idea because bone of the snake is rare. We didn’t get snakes bone between 150M -100Million years so we didn’t get clear idea about how it lost its leg it is mistry.
Researchers found two type of snake that has leg and they lived in different locations one is under water another is on the ground and due to earths evaluation the answer for this question is mistry. We doesn’t have exact answer for it.
TRY TO GIVE LEGS TO SNAKE BY ARTIFICIAL
By the research for growing leg and hand the gene called “SONIC HEDGEHOG” is shortly called as SSH it plays a role to grow legs and hand not only snake for all living organism including human also. And HOXD13 enzymes is used to grow fingers for all living organism .
The snake has it both SSH and HOXD13 but it can’t promote (enhancer) is less so it is growing but not visible it is tiny and not growing large and lost it now a days living snake .
The scientist try to give enhancer and retrive the snakes leg the research is going on . They try to introduce in rats egg and now research is doing on.
They found that python have small leg while laying eggs, but it doesn’t have enhancer to develop the legs and finger to the snakes.
ALSO LOST EAR
Though it lost legs and it can’t stand so it is always on touch body with ground so it can here every vibration on earth so need of ear is not nessasary for it so it lost its earing power and finaly lost its ear.
Though it does not have ear to hear it feel the vibration on earth and survives.
