I call you to think about this question with no prejudice. It is very doubtful whether the first DNAs and living issues originated (by the dictate as you believe) by any other way than from a mineral super-cytoplasm (see the LOH-Theory).
Because this is so, I consider by no means impossible that, under some special conditions, rather simple “parasitic” DNAs and living issues could appear within the inter-cellular cytoplasm and, may be, at the boundaries of some tissues. I think it cannot be excluded that the so-called cancer cells can come into being by a similar mechanism at the boundaries of tissues, may be, in some cases; thus, the new genome originates rather than the healthy genome transforms.
Are there any principal objections against such a possibility?
Yes, Victor, there are couple of objections. First one: "cells from cells". In current biology, not at the 3.5 billion years ago. Second, this DNA you are imagining ( on "the boundaries of tissue" ) will be eaten, internalised, by cells of that tissue. That's what cell do with intracellular environment, suck everything useful in and digest it.
Thank you, Dmitry. This answer is important. Are you sure that you are right under any conditions? At 3.5 billion years ago, voracious cells also were in the super-cytoplasm. What is about kinetics? Is the eating obligatory faster than the replication and mitosis? Yes, "cells from cells" but first cells were pioneering. Meanwhile, the discoveries in sciences were up to now made by those and only by those who had prejudiced the opinions formulated in last centuries. In our country, they say: "trust but verify".

Sure, Victor. There is always a chance for change of paradigm, if strong data support a new one. And indeed I am proclaiming current one, because I have not seen (read) anything to a contrary. Note, that I am not a specialist in Origin of life in any way. Good luck with your research! :)
O’Key! The assurance is subjective but the reality is objective. Indeed, in the world that is around us, a number of things occur which neither you nor I seen (read). And these things, among other ones, are the subjects for detection and studies. Some people believe that the today scientific paradigm around them is forever, but other researchers know that scientific paradigm changed in the past and will change in future.
I write about one of the possible (maybe, of a low probability) sources of cancer for those who think about this; you live in another paradigm; sorry, this means that I write not for you.
And, inter alia, it is doubtful whether it is possible to understand the essence of a natural phenomenon without knowledge of its origin and development in time.
