Nature can copy DNA easily, but not perfectly. Thats how mutations arise.
Implementing the DNA to an actual physical body is far from perfect. In my 7
years working as a doctor I have not met a single patient without any moles,
and thats only surface imperfections.
Furthermore the way nature does it is building from scratch with one cell
with inherited characteristics (mitochondrias, Golgi-apparatus etc.) and a
new unique set of DNA. Above the level of single-cell organisms nature has
never afaik made a copy of an already existing being with an active neural
system.
Scanning and copying a neural system without interefering with its ongoing
electrical activity is so far beyond what is currently possible to us that I
cant see any reason to look upon it as anything else but a thought
experiment.
