^_Abstract

Though Darwinian theory dramatically revolutionized biological understanding, its strictly biological focus has resulted in a widening conceptual gulf between the biological and physical sciences. In this paper we strive to extend and reformulate Darwinian theory in physicochemical terms so it can accommodate both animate and inanimate systems, thereby helping to bridge this scientific divide. The extended formulation is based on the recently proposed concept of dynamic kinetic stability and data from the newly emerging area of systems chemistry. The analysis leads us to conclude that abiogenesis and evolution, rather than manifesting two discrete stages in the emergence of complex life, actually constitute one single physicochemical process. Based on that proposed unification, the extended theory offers some additional insights into life's unique characteristics, as well as added means for addressing the three central questions of biology: what is life, how did it emerge, and how would one make it?

 Concluding remarks

Darwin's contribution to modern scientific thought is profound and irrevocable. It has forever changed man's view of himself and his place in the universe. By demonstrating the interconnectedness of all living things, Darwin brought a unity and coherence to biology that continues to impact on the subject to this day. But a paradoxical side product of that extraordinary contribution with its specific focus on living things, was that it resulted in a distancing between the biological and the physical sciences, one that continues to afflict the natural sciences. The disturbing result - despite the enormous contribution of the Darwinian theme, Darwinism remains unable to explain what life is, how it emerged, and how living things relate to non-living ones. The challenge therefore is clear. The scientific goal - the relentless striving toward the unification of science - requires that the chasm that divides and separates the biological from the physical sciences be bridged.

In this paper we have attempted to demonstrate that by reformulating and incorporating the Darwinian theme within a general physicochemical scheme, one that rests on the concept of dynamic kinetic stability, the animate-inanimate connection can be strengthened. What the general scheme suggests is that life is, first and foremost, a highly complex dynamic network of chemical reactions that rests on an autocatalytic foundation, is driven by the kinetic power of autocatalysis, and has expanded octopus-like from some primal replicative system from which the process of complexification toward more complex systems was initiated. Thus life as it is can never be readily classified and categorized because life is more a process than a thing. In that sense Whitehead's process philosophy [65] with its emphasis on process over substance seems to have been remarkably prescient. Even the identification and classification of separate individual life forms within that ever expanding network seems increasingly problematic. The revelation that the cellular mass that we characterize as an individual human being (you, me, or the girl next door) actually consists of significantly more bacterial cells than human cells (~1014 compared to ~1013) [66], all working together in a symbiotic relationship to establish a dynamic kinetically stable system, is just one striking example of the difficulty. As humans we naturally focus on what we identify as the human component of that elaborate biological network, but that of course is an anthropocentric view, one that has afflicted human thinking for millennia. A description closer the truth would seem to be that life is a sprawling interconnected dynamic network in which some connections are tighter, others looser, but a giant dynamic network nonetheless. And it is life's dynamic character that explains why identifiable individual life forms - small segments of that giant network - can be so fragile, so easy to undermine through network deconstruction, whereas the goal of creating life is such a formidable one.

A closing remark concerning life's complexity. Life is complex - that is undeniable. But that does not necessarily mean that the life principle is complex. In fact we would argue that the life principle is in some sense relatively simple! Indeed, simple rules can lead to complex patterns, as studies in complexity have amply demonstrated [67, 68]. So we would suggest that life, from its simple beginnings as some minimal replicating system, and following a simple rule - the drive toward greater dynamic kinetic stability within replicator space - is yet another example of that fundamental idea.

A final comment: this paper has discussed the concept of dynamic kinetic stability in some detail, and the question as to which stability kind - dynamic kinetic or thermodynamic - is inherently preferred in nature, could be asked. There is, of course, no formal answer to this question. In contrast to thermodynamic stability, dynamic kinetic stability is, as noted earlier, not readily quantifiable. Nevertheless an intriguing observation can be made. Since the emergence of life on earth from some initial replicating entity some 4 billion years ago, life has managed to dramatically diversify and multiply, having taken root in almost every conceivable ecological niche. Just the bacterial biomass on our planet alone has been estimated to be some 2.1014 tons, sufficient to cover the earth's land surface to a depth of 1.5 meters [69]. The conclusion seems inescapable - there is a continual transformation of 'regular' matter into replicative matter (permitted by the supply of an almost endless source of energy), suggesting that in some fundamental manner replicative matter is the more 'stable' form. What implications this continuing transformation might have on cosmology in general is beyond both our understanding and the scope of this paper.

Interesting ...but does it address what circumstances collected so to speak the available materials for the autocataylitc event..is that event post Abiogenesis or the start ..  is the hypothesis simply moving a measurement point of a start  reference up and down  the scale and not addressing mechanical pressures and enviroments/ habitats  caused by mechanical pressures  that can only considered unreatable   there effects on a chemical process  in every sense would be random  and prolonged ....its the mixing of the soup not just the ingredients and how the ingredients interact..The  actual process remains unknown simply because the random mechanical pressures and circumstance  are unaccountable in there number and originate for most of the time from the totally unique effects of its totally unique solar system I believe its these unaccountable mechanical pressures on a chemical process ..as you mention the chemical process is as much at the mercy of  enviromental pressures as is evolving biology... if a biology2 is not expected to produce another giraffe why would a chemical process produce another biology or anything that we could consider biolgical ...

Moderator Note

From rule 2.5

Stay on topic. Posts should be relevant to the discussion at hand. This means that you shouldn't use scientific threads to advertise your own personal theory

Rule 2.10

Keep alternative science and your own personal conjecture to the appropriate forum (Speculations). Threads in the ordinary science forums should be answered with ordinary science, not your own personal hypothesis. Posting pet "theories" in mainstream science forums is considered thread hijacking.

This does not address the discussion in the OP, so it is a hijack. Further it is based on your personal conjecture, so it's inappropriate for discussion here. Lastly, it's a topic you were told not to re-introduce, after 4+ pages of fruitless discussion.
