Why do genes mutate?

Pathology 44 years experience
Random: Every once in a great while, a random event or some form or radiation or a chemical will cause one or more bases in a strand of dna to differ from its origin. From the point of view of the design of life itself, without the ability of the genes to mutate, new forms of life could not develop by natural selection, but every person with genetic disease or cancer pays the price for this mechanism.
