Maybe, They Can't Breed Because They're Not Related to Begin With

   I remain tentatively in the camp that says evolution happened, just as they say it did. Only, I say God was behind it.
   But, I certainly find a lot of arguments against evolution. Last night, as I was going to bed, I thought of perhaps as big of an argument against evolution as I have ever ran across.
   Very few species can interbreed. The ones that can, are so closely related, perhaps a little evolution did occur. Now, I can't see too much reason a lion and a bear shouldn't be able to breed, and produce a, liobear or whatever you want to call it. It seems a cross breed could come out of it.
  But, nope, it'll never happen.
  Now, if we all descended from the same one-cell being, if all the animals on earth are related, then how does it come to pass that they can't interbreed? With any creature, the descendants biologically can breed with each other. Mules being one of the rare exceptions. What happens, is you have the mother's DNA and the father's DNA, and the offspring is part from one and part from the other. You can go down the species history, and while there might be some changes -- some evolutions, if you want to call it that, such as Chinese and American Indians and Blacks and Caucasians -- still, they all can still interbreed, and the offspring will take its features part from one and part from the other.
   So, where going down the timeline, two creatures diverging from a single common ancestor, does it happen that they become no longer able to interbreed? And, why can they no longer interbreed? Is it because their DNA isn't compatible? That doesn't answer the question. It only restates it, for we know it must have something to do with their DNA. Otherwise they would be able to breed.
   But, given that it has something to do with their DNA, still, the DNA of any two parents will not perfectly match. Why is it the two parents can breed even though their DNAs do not perfectly match?
  So, what of this? Two species evolve from a common ancestor, yet somewhere along the line, lose their ability to interbreed, despite the fact they carry in them common genes from that common ancestor?
   Maybe, the truth is, they can't interbreed because they were never related in the first place.
