A team of paleontologists found that nocturnal was the ancestors of modern snakes. It indicates that world’s first snake emerged nearly 128 million years ago.
Earlier, a few studies suggested that snakes were evolved in water. However, a new study rebuff all the previous misconceptions related to origin of snakes. It proposes that the first slithery reptile used to live on land instead of water. They emerged during the Early Cretaceous era along with mammals and birds. They were mostly found in forested region of North America. At that time, the area was known as Laurasia.
Allison Hsiang, a researcher at Yale University, explains the study. He states that nocturnal snakes had small hind limbs and legs. However, these organs were not used for the purpose of locomotion. As the time passes by, the little legs of snakes gradually disappeared. Presently, these legs can be found in boas and pythons.
Researchers from Yale University analyzed more than 3,400 living snakes for the study. They examine the genetic configuration and fossils of dead snakes as well. The primary aim of the study was to form a comprehensive ‘family tree” of snakes.
