replyGood source that develops on this?
I'm not 100% but I think they are referring to the fact that ribosomes are highly conserved across species.[0]

There is a chance that before 'LUCA' there were many dead ends and we ended up on the lucky branch by definition, and we don't actually know much about what happened before then so there is some possibility that what you are seeing there is the single largest example of 'survivorship bias'.
