Evolution is a FACT, but the explanation of its mechanism (like darwinism…) is no more than a mere theory whom the arguments are not very convincing nowadays, and needs some major improvement…
So you don’t think that natural selection does a handy job of explaining changes in organism populations? Hmmm… back to class with you!!!
Seriously though, the original poster wants some background about this, so maybe I can cook some up, seeing as how I’ve been involved in many of our online debates here at T-Nation about this.
Not only is it possible, it is all but assured. Observation has proven that large unbound systems (like a planet which is continually bathed in energy), given enough time, will order themselves somewhat. For example, the Miller-Urey experiment. There is nothing supernatural about this, it is the natural way of the universe.
But what about the second law of thermodynamics?
Don’t take it the wrong way. Energy and order are intrinsically linked. Allow me to quote from talkorigins.com:
“Failure to understand that in thermodynamics probabilities are not fixed entities has led to a misinterpretation that is responsible for the wide- spread and totally false belief that the second law of thermodynamics does not permit order to spontaneously arise from disorder. In fact, there are many examples in nature where order does arise spontaneously from disorder: Snowflakes with their six-sided crystalline symmetry are formed spontaneously from randomly moving water vapor molecules. Salts with precise planes of crystalline symmetry form spontaneously when water evaporates from a solution.”
Just remember that the second law actually explains the mechanism for order as well as disorder, it does not disallow it. Second law good. Without the second law, we don’t have energy exchange.
Here’s something cool to consider: those conditions which gave rise to prokaryotic life and thus, eukaryotic life are not necessary to create order from chaos. There’s still plenty of freaky biological shit going on, and here is the third kind of cell which some of y’all may not know about yet:
The “bacteria” in this group are alien and weird in that they exist comfortably in places where no other life form would even have a chance. The discovery of these freaks has actually helped us quite a bit… the polymerase chain reaction technology that is of such good use in my field of medical technology was spawned by the discovery of “thermophiles”.
The point is, given enough time and energy, life WILL happen… even in what we might consider impossible conditions. It is not some crazy one in a trillionty gazillionty occurence. The more we find out about our planet, the more we realize that life is more likely to be ubiquitous in a galactic sense.
I would not be surprised if we somehow discovered that there are exotic thermophilic archaea who sprung into existence on Venus, and have been hanging out for the last 4 billion years, waiting for us to discover them.
