Super kewl!
This is cool 21st Century research.
I’m still amazed when a cut heals.
Wasn’t it said once that the wages of sin is non-regeneration?
Mutations DO NOT create new abilities, they only destroy capabilities.
Most of your (and even single cell organisms) DNA is switched off.
It can be switched ON by environmental factors - this is called EPIGENOMIC affect.
Google it EPIGENOMICS
You have been lied to - constantly told that mutations allow adaptation. It’s not true.. Epigenomics is PROVEN true.
Essentially, the “junk” DNA never was “junk” it’s additional capabilities that get switched ON when needed. A methyization process binds with the DNA to enable genes.
This is real science, proven, reproducible in a lab. Not theory like the idea you can create functions from random mutations.

Having the “genes” is only a small part of the picture. Decades ago, there was a research paper describing how the optic nerve developed. If found that the nerve growth was controlled and sometimes stopped by a chemical the body produced to keep the nerve from growing in unwanted areas. That chemical would be the result of many more genes, which are poorly understood.
Also says the retina is an extension of the cns.
So... would be cool to discover that the brain proper, and the chord can also do this?!
Opens up a whole new world of injury mending.
