I have to be the 7th grade science geek here. -_-
Mutations can be caused either by a mistake made in the body, or a mutagen, something that makes the base, sugar, and phosphate group (nucleotide) (Adenine, Guanine, Thymine, Cytosine.) For example, sunlight, or UV rays, can cause a genetic error which results in cancer. The effects of a mutation can be good or bad, and the three types of mutation are substitution, elimination, or insertion. However, mutations do not cross-breed animals, and chromosome counts proves so. If we shared characteristics, that would be genetic engineering.
