It can only be explained by a Creator who pre-programmed specific traits in the genetic codes of all living things. A modern scientific design argument . This particular skeptic believes that he has found an example of 'new information' arising by mutations and natural selection. Conclusively shows that there is no mechanism for evolution, and that life could only evolve by chance in fairy tales, not in the real world of true science.
New traits do appear, at the molecular and morphological level new proteins, new pigments, etc.
These are novelties. Two parents with blue eyes will generally produce children with blue eyes, and likewise two plants with white flowers will generally produce new plants with white flowers, but sometimes that seedlings with red or purple flower turns up, not because a recessive allele has been revealed, but because a mutation has altered an existing pigment or biochemical pathway to produce something entirely new, that has never existed before. As an example, there is nothing like an ear of corn in any other species of grass. It seems to be entirely unique in the plant kingdom. And yet there are three or four species of grass, very similar to corn in their overall growth, but with typical grass-like reproductive organs.
