From wiki huh? Nice. My mistake I meant to say Donkey and not mule. In a way you proved my point. Let me explain. I am sure you won't understand, but here it goes.
There is no scientific evidence that a species can change the number of chromosomes within the DNA. The chromosome count within each species is fixed. This is the reason a male from one species cannot mate successfully with a female of another species. Man could not evolve from a monkey. Each species is locked into its chromosome count that cannot be changed. If an animal developed an extra chromosome or lost a chromosome because of some deformity, it could not successfully mate. The defect could not be passed along to the next generation. Evolving a new species is scientifically impossible. Evolutionists prove that getting a college education does not impart wisdom.
When your dog is going to have a litter, don't worry that she will have a litter of monkeys or cats. She will always have a litter of puppies. The fact that she will have puppies was determined when her chromosomes joined with her mate's chromosomes at conception. You see, a dog has only 22 chromosomes, whereas a monkey has 54 and cats have 38. Half of the total number of chromosomes are contained in the female reproductive cells and half are contained in the male, so the exact total number is brought together in the offspring.
Humans have 46 chromosomes. This chromosome count is a steady factor. This determines what is called the "fixity of species" because the chromosome count doesn't vary. People always give birth to people. Dogs always give birth to dogs, etc. The genes can produce variety within the species but cannot result in a different species. Genes allow for people to be short, tall, fat, thin, blond, brunette, etc., but they are still all human beings. The chromosomes make crossing of the species an un-crossable barrier. This certainly would hinder any evolution. Dogs cannot breed with cats. This fact stops evolution dead in its tracks.
Sometimes two species are close enough to crossbreed, but the offspring are usually sterile. This is the case when horses and donkeys crossbreed. A male donkey (jackass) and a female horse (mare) will produce a mule. Farmers often preferred mules as work animals prior to the development of the farm tractor. A hinny is the offspring of a female donkey (jenny) and a male horse (stallion). The hinny and mule usually cannot produce offspring. These animals show that evolution is not possible.

I'm not a geneticist, so I don't have an original argument of my own for rebuttal. However a quick google search has brought me to many explanations of how chromosomes numbers may not be the road block to evolution that you propose. I'm happy that you pointed this out to me, however, and I'm going to enjoy studying the matter further.
See, this is how science works, a question like "how can animals evolve into different species if they have different chromosome numbers?" leads to investigation into the matter and new discoveries. Religion is content to say "god made it that way" and leave it at that. By raising questions like these you are becoming a more scientific thinker. The next step is to come up with possible ideas that could answer the question and systematically test them. But I realize that is not your intent. Your intent is to raise these questions to trip someone up in their arguments rather than actually find something out.
