I speak my own mind .... I have never sided with any certain view. I will say this there are many people commenting on this topic and they all have a right to their thoughts because to them that is what they believe in.
I read the posts and I comment about things that match my own beliefs..
Just because we don't see eye to eye on things does not constitute for labeling me or bashing me ...

I wasn't judging you North, I was agreeing to your astute and wise consideration of something more than those who might otherwise think such ideas are radical. Sorry my being facetious about that radical part and not clarifying.

When you cross a 48 chromosome horse with a 46 chromosome donkey, you get a 47 chromosome mule which is sterile. Mules cannot produce other mules. But evolutionists would have us believe that our earliest 46 chromosome ancestor managed to have 46 chromosome FERTILE children all by herself or himself.
So what drives evolution, then, if not random mutations being selected non-randomly?

Barriers To Interbreeding
Now differences in chromosome number do not serve as reproductive barriers between all species. For example, lets look at some of the equine species ( horses and donkeys). Domesticated horses have 32 pairs of chromosomes and Donkeys have 31. Yet, they can produce offspring, mules, which have 31.5 pairs of chromosomes. One of the horse chromosomes goes unpaired. Wild mountain zebras have 16 pairs of chromosomes, while the last species of wild horse (Przewalski's Horse) has 33 pairs. However, all of these equine species can produce hybrid offspring. In all of these crosses but one, the offspring are sterile. It has long been argued that this sterility is due to the difference in chromosome number, but hybrids of the wild (33 pairs) and domesticated horse (32 pairs) are fertile, and have 32.5 pairs of chromosomes. So clearly, something more than just differences in chromosome number is contributing to the species interbreeding barrier.
Translocation
Translocation is what happens when two chromosomes that are not part of a pair get stuck together as if they were a pair, and exchange segments. If the segments that get exchanged are large enough, you can have most of both chromosomes moved onto one single chromosome, as shown below. In this figure, the blue and red boxes are cartoons of two different chromosomes. The black dots in their centers represent the "centrosomes" where the cell attaches filaments that drag the chromosomes around. When these chromosomes cross-over, the result is two chromosomes are very different size. One larger chromosome, contains almost all of the genetic material of the two chromosomes, while the other smaller chromosome contains almost none. In this example, the material from one chromosome has been moved or "translocated" onto another chromosome. In dramatic cases like this one, the resulting tiny chromosome is usually lost, and the resulting chromosome count is reduced by one.
Summary
So, to wrap up, changes in chromosome number are not really caused by mutations. Mutations are changes to the DNA sequence that occur during DNA replication and repair. Some people might argue that translocations result in large additions and deletions of DNA sequence, but that is not what people are generally referring to when they use the term mutations. Instead, changes to chromosome numbers are brought about when errors occur in the process of chromosome duplication (of which DNA replication is only a small part).
Finally, it seems like changes in chromosome number are not the ultimate barrier to species interbreeding. Some hybrids of species with different chromosome numbers are fertile, and chromosome pairing is still possible even when the number of chromosomes is different.

If we look at the example of the Peppered moth we can see how a species evolves a "needed" trait, rather simply. In this case the moths have changed to a far more suitable colour to avoid predation. They didn't choose it, but the most camouflaged individuals weren't eaten, and so their mutations became more and more common, until their mutated camouflage became the most common camouflage.

Yeah I understand that dave, this much is obvious, but what I meant by 'mystery' is, what causes the mutations that result in genetic change which suit the specific adaption need.
With my example, herein lies the mystery, atleast to me, How is the mutations causing genetic change, resulting in a smaller gape width in the black snake exactly what seems to be needed, after the fact of the introduction of invasive toads?
Is this sheer coincidence? Is this random, or is it the 'being non randomely selected' part ?
The mystery is what is doing the selecting non randomly.

The mutations don't simply appear at the moment they're needed.
The thing is, mutations happen all the time, but most of them are neutral - they don't affect the organism's breeding chance at all. Some snakes probably already had the smaller gape. But when a new pressure - the toads - is introduced, previously neutral mutations become beneficial. Those who don't possess the newly-beneficial mutation die out.
It isn't that the mutation suddenly appeared. It's just that it wasn't selected for prior to that time.
. . . imagine a puddle waking up one morning and thinking, ‘This is an interesting hole I find myself in. Fits me rather neatly, doesn’t it? In fact it fits me staggeringly well, must have been made to have me in it!’ This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, it’s still frantically hanging on to the notion that everything’s going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.
Obviously, I'm focusing more on the opening lines than the ending. It isn't that the world is conducive to life - it's that life can adapt to almost anything, given enough time. And time is something life has had in abundance.
Creationism cannot co-exist with evolution. Creationism attacks science as a whole, not just evolution, and seeks to replace science rather than operate by science.
