Perhaps it was unwise to use the term dna damage yes. I used it to mean any deviation from the initial dna of the fertilized egg, including breakage, point mutations, missing chromosomes, viral insertions and probably more I can't think of right now. Edit: I suppose those are all called mutations. Somehow I thought mutation meant a small local change only.
