That is one nice thign about DB. It really isn't a tirade against either Intelligent Design or natural evolution. It takes neither side, and simply is what it is, with no alterior (or is it olterior?) motive.
Yeah, reminds me of reality itself. With the past shrouded by time and change who can say what exactly started it all :D
Inteligent Design - Someone(God, aliens, other) created life as we know it upon earth, proponents believe roughly that the sheer complexity of life and even simple life could not arise through evolution alone.
Evolution - (Paraphrased possibly not exact)Chance mutations arise that either increase an organisms overall reproductive efficency or have a neutral affect, allowing bennefial or neutral mutations to increase in frequency. Deleterious mutations are weeded out.
A bit of a troubling question is how all the more or less random chemicals/compounds began replicating in the first place.
IMO
My take on it all is that the message(dna/rna/other) being carried through time is simply trying to maximize it's time existing in general.
Simply more identical messages are bennefical to a degree(when loss is possible) until the sheer identicality leads to losses. Then it becomes benneficial to have similar messages that share the same basic traits but perhaps yield slightly different effects. Then of course it becomes useful to more deliberatly share genes amongst a species allowing overall error fixing(yes, I know the dna/rna is capable of impressive feats in this regard but there is a wee bit of a logic problem if the error fixing sites themselves are messed up).
For us higher level lifeforms numbers of sperm released probably respond to dangers facing a population. If danger is high larger numbers are released increasing competition, lower means dangers are less and dna can be more liberal in the possible species traits that can be represented.
Ie. In times of plenty expand dna expression, in times of scaracity deminish it.
We're seeing this currently in our society. It's not really an issue of worse genes being expressed more often its an issue of dna trying to more completly express itself. Basically the dna will select for increasingly more fit dna in dangerous times; while selecting for less/basically fit dna in plentiful times.
The question of rapid spread for species is probably answered by the flipside of massive deaths. If a new species is not only more efficent but also directly deadly to another, the older species niche will be subsumed and the species consumed vastly accelerating the spread of a new species.
Junk Dna, epigenetics, and Viral Cross-species gene transfer should have their own roles in species evolution expounded upon and be included in an improved overall theory of Evolution.
Alright, keep in mind the above is my own opinion, assembled from all sorts of sources. Flames to a minimum please, as this is mostly largely guesswork on my part anyways.
I'm heading a way for a bit over a week soon, so don't be too worried :lol:
