Anybody claiming this, just don't have a deep understanding of mutations. Mutations are not a god's gift. Maths and science predict that they happen randomly, and most of the time they carry terrible consequences.
Lets take for example the people that inherited the butterfly skin syndrome. With a so fragile skin that it rips from the shoulder to the waistline at the minimum brush. Do this girl or this boy wanted to "adapt" to have a insufferable pain all the days of this life?
I seriously doubt that anybody would have asked for that. Lets be serious.
