I don't want to get into the usual process of getting a link to a fossil that might fit the bill of surviving in such an environment and being told that is proof of how it happened, I understand that most all answers would be speculations and assumptions but it just seems to me that the odds of randomly mutating all organs necessary to survive (not hindered any more than it's previous form) in the current biome and a new unknown biome on top of being transported to said unknown biome within the distance of another said creature of the opposite gender that went through similar random mutations...
You're making a couple of assumptions here that are simply incorrect. For one, mutation is
random, in that a given change is vastly unlikely to occur exactly where / when it will offer an immediate advantage to the organism carrying the mutation. But natural selection is decidedly not
random, and will continually eliminate organisms that carry disadvantageous (for a given environment) mutations while correspondingly favoring traits that offer even the slightest
I may be mistaken, but you seem to imply that mutations often result in drastic morphological changes to an organism (like organ systems). In fact evolutionary theory predicts (and is borne out in the fossil record and genetics) that such changes are always incremental, allowing them to co-evolve with the other traits needed (for example) to transition from sea-dwelling to land-dwelling.
For another, you seem to have this concept of animals undergoing mutation / natural selection in isolation. But evolution acts on entire populations
simultaneously, so that there are thousands upon thousands of organisms carrying a given mutation or set of mutations. In the case of sexual reproduction, at any given time in a species' history, for an individual to find a suitable mate is not a major problem.
you get the point, speculation about what the animal looked like or what it could have been, I've seen before but the actual process of chance that would have taken place to go through a drastic change of environment like the sea or a river to a even just a pool of mud and then land. I know the answer is probably that we do not know how but it happened, however that isn't really more helpful than saying a puzzle piece was made randomly and somehow fit another randomly made 4 surrounding pieces.
You have a concept of evolution that is seriously distorted. You are also quite ignorant of the amount of evidence we have for the ongoing process. In fact, the progress of life (vertebrate and invertebrate) from sea to land is quite well understood at this point. Here are some links.

Frankly, that you're essentially asking the same kinds of questions you asked in this thread (http://whywontgodhealamputees.com/forums/index.php/topic,21001.0.html
) makes me wonder about your sincerity in looking for answers.
