Not only is it not universal knowledge, there are substantial cohorts of people who will vehemently deny that it is true. In fact, there are people asking for additional evidence in other branches of this very discussion!
I mean, nothing that would be relevant to the question at hand, in my opinion.
Because the topic still is as linked above, and subsumed in this simple proposition: The genome varies from cell to cell.
Great. What a discovery! More news at 11!
Or is someone seriously arguing that genetic mutation is not universal knowledge?
(Excluding "flat-earth" level stuff, but I would assume that as given on HN. Maybe I am wrong again)
Well, no. But there are a lot of people who vehemently deny that humans are in any way analogous to ants.
