It kinda had to at some point right? DNA didn't exist until something other than DNA led to it.

That's abiogenesis in a nutshell.

Did somebody ever try to recreate the bion experiments? I'm pretty sure Reich is considered a quack nowadays, but makes sense to just observe things with a good enough microscope and patience, one could observe abiogenesis in some form

If you're aware of Reich you might already have heard of René Thom's theory of morphogenesis and how he modeled it. If not see below.

The result is an extraordinarily simple strand of DNA, consisting of the repeating sequence C-A-C-A

I thought that image looked familiar, and indeed it is by the author of The Machinery of Life (maybe from the book itself but not directly attributed)

Maybe this is how organelles form like the hemifusome and mitochondria.

Ok, fascinating, but why the repeating info in the article?
