Coding for Limbs in Snake Genome?

Several hundred million years ago, a common ancestor of mammals, birds, and reptiles evolved and started growing an extension of the body known as a phallus, or male genitalia. In a recent study published in the journal Developmental Cell, scientists have found that the genes used to develop a phallus in the embryonic stage of an organism are also used to develop limbs. Non-coding DNA called enhancers control gene expression in phalli and limbs. It has been discovered that these enhancers found in limbed animals are present in the snake genome.

This raises a few questions. Do snakes have the potential to grow limbs someday? Will snakes evolve into limbed animals in the near future? For now, scientists conclude that the limb enhancers found in the snake genome are used for phallus development, but that doesn't mean that it is impossible for snakes to grow limbs. I personally think that someday, snakes will be able to grow limbs and not through mutation. When that day will be, I don't know, but although we as a human race have learned a lot about the world we live in, there is still a lot we don't know about.
