Too true.Spontaneous mutations never introduce anything into DNA but take away from existing information and basically mess it up.Useless to the theory of Hominoids to Hominids and other such nonsense.

I love the "in very simple biology terms, it ain't gonna happen". Are you aware that that isn't a biological (or even proper English) term? I'll assume it was a joke.
So, the people who wrote the encyclopedia article you're referring to are scientists, who probably believe in evolution (around 95% do). And you, not wanting to, trust one thing they "say" and not another. It's called cherry-picking.
What do you mean by spontaneous mutation? I bet everyone on the planet has some genetic mutation, i was born without the second tooth from the front on the right side for example, which was genetically passed on from my father. I don't know where he got it, maybe spontaneously? Even if you believe in creation, something would have to had happen. And, i had to spend like $4000 to get a fake put in, so if that's in God's plan, i'm pretty pissed!
Seriously, bottom line, do you think you're smarter than scientists? Just say so. It's not a crime, just be honest.

The horse and the donkey cannot produce fertile offspring because they had a recent divergence including a change in chomosome number. As a result, mules have an unpaired chromosome.
About one in 1,300 humans have a fusion of chromosomes 13 and 14. The causes significant fertility issues that are identical in process to the horse/donkey problem.
Spontaneous mutations occur all the time. Here is an example of a spontaneous, beneficial, information increasing mutation:

Spontaneous mutations appear constantly! This is a known fact, observed thousands of times in both plant and animal species! Do a bit of basic reading before you make such absurd statements! And natural selection based on those mutations has also been observed thousands of times, both in the laboratory and in nature.
And what about the mule? It isn't a mutation. It's a hybrid, an artificially produced cross between two other species. Such hybrids also occur in nature, such as coydogs, which are crosses between dogs and coyotes. This has nothing to do with spontaneous mutations however.

Biologists argue with me and tell me that the tree metaphor is better, more elegant, but better, more elegant doesn't always mean correctly interpreted. Some things in nature are sloppy. I think the same evidence can be explained by each creature developed from an earlier version of itself and not from another kind of creature just as the tree develops from a seed that becomes a sprout and mammals develop from two cells becoming a zygote. Intelligent design or not, it would still answer the question of how we developed if you don't believe, as I do, that we were not, plants, animals and humans, spontaneously created as we appear today.
I don't mind at all and invite anyone who can explain to a non-specialist why this idea cannot work under any circumstances.

I think that it's apparent that you have not even read anything about evolution if you could only come up with this example. In the first place, it doesn't mean anything that a hybrid cannot reproduce. Hybrids between different sub-species within a species are known as intra-specific hybrids. Hybrids between different genera are sometimes known as intergeneric hybrids. Extremely rare interfamilial hybrids have been known to occur (such as the guineafowl hybrids). Hybrids are not due to mutation. Spontaneous mutations are rare, but they do not have to be numerous over such enormous spans of time.

Here's a simple example. It's simple for you. Ecoli evolving. Micro-evolution. Many micros make macro-evolution. Here is the example proving simply that evolution is fact. The genetic mutation in the DNA of the ecoli has changed and environmental exposure kills all of the original ecoli whereas the genetically mutated ecoli survive:

Just one example. I know it doesn't prove the origin of man but it's just an example of evolution as a fact.

We also share about 50% of our DNA with bananas and that doesn't make us half bananas, either from the waist up or the waist down.
The genetic difference between human and his nearest relative, the chimpanzee, is at least 1.6%. That doesn't sound like much, but calculated out, that is a gap of at least 48,000,000 nucleotides, and a change of only 3 nucleotides is fatal to an animal; there is no possibility of change.
if we were to take this idea of similarities to determine which animal is most like us, we would come up with dire results. Take, for instance, our number of chromosomes (46). Two of our closest ancestors would be the tobacco plant (48) and the bat (44). Furthermore, because the chromosomes in living matter are one of the most complex bits of matter in the known universe, it would seem logical to assume that organisms with the least number of chromosomes are the end result of millions of years of evolution experimenting to increase complexity in living organisms. Therefore, this would reveal that we started from penicillium with only 2 chromosomes, and slowly evolved into fruit flies (8), and after many more millions of years we became tomatoes (12), and so on, until we reached the human stage of 46 chromosomes. Millions of years from now, if we're fortunate, we may become the ultimate life form, a fern, with a total of 480 chromosomes.

Evidently, you are not familiar with viruses. Let me enlighten you. Have you ever had a cold? Chances are that you have. But you have never had the exact same cold. The virus spreads to other people, surfaces, etc. It mutates into another virus all by it's lonesome, and you get the cold again. It is not the same cold, but it is a mutation. This is also what makes AIDS(also a virus) so hard to cure. NEXT!

Whatever can you mean? Mule's "ain't gonna happen"? Mules happen all the time. In fact mules are a great example of evolution in action (or at least the effects of common ancestry).
