Prime editing allows precise changes to be made to DNA.

A new way of editing the code of life could correct 89% of the errors in DNA that cause disease, say US scientists.
The technology, called prime editing, has been described as a "genetic word processor" able to accurately re-write the genetic code.
It has been used to correct damaging mutations in the lab, including those that cause sickle cell anaemia.
The team at the Broad Institute say it is "very versatile and precise", but stress the research is only starting.

We always have been: this just lets us potentially do so in a planned, precise fashion.

Messing with evolution .. what to say?

The way I understand it is that the biggest ethical issue is that we do not know yet what such changes could cause.

Are you suggesting that evolution is supposed to have some particular sort of outcome? What are you suggesting? I mean, tuco, there's a lot of stuff we don't know, so remarking on that doesn't create any big waves by itself. Crumple creates plenty of great posts that should have ominous movie music over them; no need to add to the din.

Why ask me and not mingthething?

No. I am not suggesting anything. I am just parroting what I've heard about this issue at hand. Apparently, He Jiankui was messing with a gene without being able to guarantee that the changes he made will have only the desired result. It's like giving a patient a drug without knowing its side effects, which is arguably unethical.
