But when I made my first post in this thread the title of the thread was "Thermodynamics & Abiogenesis".
But the issue of a mechanism for using free energy to locally decrease entropy isn't directly a thermodynamic question. I'm sure we all expect that the mechanism for OOL will have to be thermodynamically "uphill".
So the second law itself doesn't pose a problem. If you agree with that then bring the mechanism issue up in a separate thread not here.
The above is a very non-rigorous look at the relationship between life and thermodynamics.
quote:Discussions of how life coexists with the Second Law usually stop there: the Second Law isn't violated because the system's not closed. True enough, but not terribly satisfying. While it does explain how life is possible in the presence of the Second Law, it hardly explains what we see everywhere we turn: life spontaneously, aggressively, irrepressibly expanding to fill every available niche in the environment, creating ever richer and more complex ecosystems comprising an ever-expanding variety of increasingly complex life forms. We don't see life just getting by in the face of the Second Law; far from it. I.e., life isn't just side-stepping the laws of thermodynamics; somehow, life is actually favored by them.
and the not-particularly-rigorous-answer?
quote:Life feeds on gradients and, in the process, helps to reduce them. In so doing, life does Nature's work. The bottom line: thermodynamic principles do not oppose life, they practically command it into existence. Life is an integral part of the universe, completely consistent with the thermodynamic principles that unite both living and nonliving matter. Life belongs*.
Your reasoning showed that you have a very little understanding in physics,read more.The second law stated that if things left unattended it will become a ruin.For example abandoned your haus and it will become a ruin.So if nobody cares about the universe,"Why it will not become a ruin"?Put this question in your coconut shell.
It is you that has very, very little understanding of physics.
That is not what the 2nd law says. It is a highly simplified example to give a flavor of what entropy is about.
It also does not imply: "So if nobody cares about the universe,"Why it will not become a ruin"
Thermodyamics does have bearing on any processes or mechanisms which affect your "haus" such as maintenance on it.
Since a "haus" is not an example that has anything at all to do with abiogenesis or evolution it is irrelevant here other than a demonstration that you don't know either subject at all.
If you wonder why it is a lousy analogy for evolution you should note that houses don't f**k. That is, in short, the difference.
If you wonder why it is a lousy analogy for abiogenesis you should note that 2x4s have no chemical affinity for each other.
When you understand those issues you will have begun to learn a little tiny bit about the subject at hand.
