Rivi 57:
It would seem that the strongest possible scenario which may have driven the evolution of snakes is a switch to a more fossorial lifestyle. Readily available food sources underground would have been reached by these ancient cretaceous lizards through burrowing and searching through tunnels and narrow crevices. Living underground would also gain the animals protection from predators. The animals would have adapted to this underground lifestyle over time through the development of characteristics previously described with the Earless Monitor Lizard.
Picture
Although it is often implied that the anatomical structure of the snake (e.g. reduced limbs and long bodies) is an adaptation for a burrowing lifestyle (fossoriality), other studies have demonstrated that the ancient snakes may have in fact been surface-dwelling and were likely nocturnal stealth hunters that foraged widely for soft-bodied prey in warm, mild, well-watered, and well-vegetated ecosystems.<ref name="evolution"
