Do I have this right? Mutation is synonomous with chance. So mutation (chance) occurs, then natural selection eliminates the harmful or unbeneficial chance and the good chance survives to enter into another state of mutation (chance) and this cycle occurs for millions of years (time). So if I say chance through natural selection and time is that an accurate definition?
Just to touch on a couple of things. There appears to be some confusion with regard to mutation so it might be better to think of it in terms of both mutation and natural variation of individuals within a species.
If you look at humanity, for example, we see a great deal of variation within and between populations. Some carry no particular obvious advantage, for example blue rather than brown eyes, whilst others, for example skin pigmentation carry developed benefit to climate.
In a given population with individual variations a certain trait can, under circumstances of environmental change provide benefit leading to an increased chance of breeding increasing the chances of a higher proportion of the next generation having that trait.
The chance element is, in the above examples, that an existing variation comes to carry benefit at a particular time in a particular environment.
With regard to the origins of life, which is outside of evolution and natural selection and referred to as abiogenesis the question at the moment is with regard to either self assembling RNA molecules or direct to self assembling DNA molecules the latter of which is currently considered to be the less likely.
We already know that long chain RNA molecules can be made to self assemble in the lab in solution (see http://news.sciencemag.org/2013/02/self-...ble-origin as an example of experiments happening a the moment). Note that this is being done in water with RNA.
This may, or may not be, abiogenesis as it actually happened but the point is not that. The point is that we do have a viable potential route for life to form without a controlling intelligence.
Ultimately whichever route you choose to follow is a personal decision but for me, to conclude a higher intelligence is really looking like the less likely option.
