Natural Selection

Natural selection
(differential reproduction genotypes)
Is the process in the theory of evolution where organisms that are best suited to their environment survive and pass on their genetic characteristics in increasing number while organisms that are less adapted tend to be eliminated.

**the rat snake has different populations in eastern North America. All compromise one specie because mating can occur between adjacent populations causing to share a common genepool.

**are well documented both by obsserving and through the fossil record!**
