I was wondering if it would be possible for someone could provide us with a clearly defined and unambiguous outline of the current iteration of evolutionary theory.
Then we can sticky it to the top of the forum and if people want to discuss its merits and/or flaws without entering into the exercise in futility which is the debate (which I shall not mention) they can. Otherwise it going to be really annoying every time one of the "science isn't happening" nuts starts a "whats wrong with evolution" thread and we have to get it moved......
I'd provide one myself but since I did geology and left uni a while back it probably won't be 100% accurate and thus leave holes.......

There's mutation and there's genotype to phenotype correspondence. A mutation might introduce a new characteristic intro phenotype, then the new mutated guy and its descendants (on average with the same kind of phenotype change) would be put to test in the real world, and on average could or not survive better then the others.
It's a huge stochastic process, and even new "fittest" guy could not survive to tell the story. Sometimes they win, sometimes they don't.
And that's it... evolution is nothing more then mutation, replication, selection... A little boring and self-evident if you ask me.
Now just apply this to a mono cellular organism billions of yrs old and there's theory of evolution.

Now how do we get this stickied to the top of the forum.........

These various traits affect the amount of reproduction that organisms manage to accomplish. Those organisms which reproduce more will increase the incidence of their traits and genes among the population. Thus, variation modifies reproduction which then determines how much that variation will be present in the next generation.
When two populations are separated from one another over long periods of time, they will tend to diverge and eventually will become so different that they can no longer interbreed, or cannot do so efficiently. This is the point at which two species diverge from one another; the same population which interbreeds within itself normally leading to two populations which cannot interbreed.
This process, repeated over the billions of years life has existed, has led to the diversity of life we see today.

Or they can somehow make it so that whenever "evolution" is in the thread title it can automatically be moved to debates.
EDIT: or if "Darwin" is in the thread title also.
It's when it comes to the r*ligious interpretation and debates it should be moved somewhere else...
