"In biology, evolution is the change from generation to generation in how common various inherited characteristics are within a population. These characteristics are encoded on genes. Competing variants of genes, known as alleles, cause different characteristics to become more common in different organisms, resulting in variation between organisms with different alleles. As these differences in and between populations accumulate, new species can evolve from prior ones. All known species are descended from a single ancestor through this process of gradual divergence." ~ Wikipedia So what is your opinion?
