    Here is a lengthy paper covering the subject of Abiogenesis....

    Chemical roots of biological evolution: the origins of life as a process of development of autonomous functional systems:
    Abstract
    In recent years, an extension of the Darwinian framework is being considered for the study of prebiotic chemical evolution, shifting the attention from homogeneous populations of naked molecular species to populations of heterogeneous, compartmentalized and functionally integrated assemblies of molecules. Several implications of this shift of perspective are analysed in this critical review, both in terms of the individual units, which require an adequate characterization as self-maintaining systems with an internal organization, and also in relation to their collective and long-term evolutionary dynamics, based on competition, collaboration and selection processes among those complex individuals. On these lines, a concrete proposal for the set of molecular control mechanisms that must be coupled to bring about autonomous functional systems, at the interface between chemistry and biology, is provided.

    Conclusion:
    In this prospective critical review, we have focused on the first steps of the process of the origins of life, which have important implications for subsequent stages. Ours constitute a non-conventional approach to prebiotic evolution, because it shifts the attention from homogeneous populations of molecules to populations of heterogeneous, compartmentalized and functionally integrated assemblies of molecules. The consequences of such a shift of perspective are multiple, both at the level of the individual units—which require an adequate characterization as self-maintaining systems with an internal organization—and also in terms of their collective and long-term evolutionary dynamics, based on competition, collaboration and selection mechanisms that are in need of further investigation.

    The fact that such compartmentalized individuals possess an internal organization allows speaking about function in a physiologically relevant sense, because one can distinguish between parts of the system that contribute in a distinctive way to its maintenance as a whole. Immediate research goals to be targeted, in this context, will be: (i) the implementation of feasible versions of these composite systems, under specific experimental conditions; and (ii) the careful analysis and characterization of the roles played by the various kinds of molecules involved in the integrative process, ascribing functional properties to each of them. In this way, the concept of function has good chances to get naturalized, opening a scientific research programme to discover its deep chemical roots. As a result, new perspectives and theoretical approaches to understand evolvability as a general property of matter, well-grounded in experimental data, should also be brought forth.

    No form in the periodic table can think .

    Life thinks .

    Try me pad . But first you need to explain the chemical evolution yourself pad . Just so that we all know that You pad understand it yourself .

    No form in the periodic table is water, either. But water is made of things from the periodic table.
    And life is made from things in the periodic table.

    And .....continue your thinking .

    True .

    And Life manipulates the periodic table in order to manifest . Hence why minerals are a part of living forms .

    Bullshit....
    As you already have been told.....
    Plus again just a reminder that this thread simply a copy of the last post here in order to put your pseudoscience bib in.... http://www.sciforums.com/threads/chemical-evolution.163475/page-10 ...and against the formal warnings by James you received.

    Nope. Sorry, that's woo. No life process relies on transmutation.

    Chemistry to Life is transmutation .

    Nope.

    TRANSMUTATION:

    physics: the changing of one element into another by radioactive decay, nuclear bombardment, or similar processes.

    How you know River has lost the argument:

    He starts looking up alternative definitions for words.

    I hope that this somewhat useful to you river?

    But.... my impression at this time is that the bulk of evolution in the universe / multiverse probably took place BEFORE the earth came into existence about five billion or so years ago.

    It’s easy enough to find the definition of photosynthesis. Why ask someone else? Essentially, it’s shuffling around carbon atoms between molecules; it’s part of the carbon cycle. No transmutation of elements is involved.

    Mod Note

    You have linked this guy (either the same link or cross linked to a post on this site with the same link) in 9 different threads.

    By any definition, that's spamming.

    Please cease and desist in doing stuff like this. If you continue to do this (cross linking to other threads where you are posting (that aren't even connected subject matter wise) constantly and spamming the same link in multiple threads as a couple of examples), you will face further moderation.
