If a single cell loves itself very much... (I know, not *EXACTLY* the very origin, but hey...)
 
I have leaned towards a mechanistic viewpoint---biology can take you only so far back--chemistry only so far forward.

In between? Vortices spinning off smokers--and micelles

Self-replicating micelles — A chemical version of a minimal autopoietic system - Discover Life

Reverse micelles hosting the internal production of the surfactant are proposed as experimentally feasible models of simple (or ‘minimal’) autopoietic systems. We describe the conditions under which these may be formed and their possible biological implications. The micellar systems considered...

A micelle is a "spherical cluster of amphiphilic molecules (like soap) that self-assemble in a liquid, forming a colloidal suspension."

I think cells came before DNA.

It doesn't take much energy for life to repair itself

"Their study, published in Proceedings of the National Academy of Sciences, reveals how the protein actively reshapes cell membranes—without requiring any external energy. The findings shed light on a fundamental biological repair process."

Since the Jyoti Singh et al paper came out of University College London, I'm a bit surprised that their Department of Genetics, Evolution and Environment wasn't involved. Personally, I like UCL biochemist Nick Lane's emphasis on proton gradients - ie: no energy source, no life. Also keen on Lane's notion of pores formed within carbonate rocks around alkaline hydrothermal vents being able to provide an external 'structure' before self-supporting cell walls evolved.
