HOW LIZARDS EVOLVED INTO SNAKES

Lizards to Snakes
Many millions of years the planet was dominated by lizards 
great and small. It was a place ruled by the laws of natural 
selection where the only way to survive was to be able to defend 
yourself with what you had. It was a constant struggle for food, 
shelter, and supremacy. It was about survival of the fittest, 
because only if you were best suited to your environment would you 
have a chance at living to reproduce. Sometimes adapting to one's 
environment could create a whole new species altogether.
During the time when dinosaurs walked the earth smaller 
lizards had to be creative to insure their survival. The dinosaurs, 
because of their size where the bullies of the earth. If lizards 
wanted food they had to some how sneak around the big dinosaurs in 
order to avoid becoming food themselves. A species of lizard known 
as the Ear-less Monitor seemed very well adapted to counteract this 
problem. Their eyes had a clear protective lens which allowed them 
to go into the water in search of food and bypass the land roaming 
dinosaurs all together.
One major problem soon faced the Ear-less Monitors in their 
quest for nourishment. It seemed that the sea dwelling creatures had 
begun to catch on to the fact that these lizards were invading their 
territory for food. The sea dwellers reacted by praying on the 
lizards who came into the water to eat. After many deaths at sea one 
smart little Ear-less Monitor decided to try another approach at 
obtaining food. This particular Monitor was picked on by all of the 
other Monitors because he and his family had arms and legs that were 
shorter and smaller than everyone else's. The would tease him and 
his family saying that their gene pool had little genetic variation. 
But he did not let that get him down.
He figured that with his stubby arms and legs that he could 
burrow under ground to find food. He used his clear protective 
lenses over his eyes to keep out dirt and rocks. He was sure that he 
could find some delicious earthworms and other things to feed 
himself. It was like an all you can eat buffet until all of the 
other short armed Monitors got the word. The short armed Monitors 
lived happily under ground while the rest of the species quickly died 
off.
Over time genetic mutations occurred which eventually left 
the Monitors with no limbs at all. They just had long slender bodies 
which enabled them to burrow easily and quickly. In order to forget 
about the torment that their ancestors had been subjected to by the 
long armed Monitors the group decided to be known from that point on 
as snakes. The snakes soon decided to give life on Earth's surface 
another chance because now they were much quicker than the dinosaurs who had devoured the
Monitors. They adapted to their new environment quickly with a leg-less mode of
locomotion. Over time they evolved and developed more defense mechanisms to become the
Snakes we know them as today.
