I want to see someone try to breed a bat from a rodent. Do all the selective breeding you wish, and induce as many mutations as you want. I want to see one shred of evidence that you can bring the species one iota of a degree closer to a bat than it is now. The evolutinist rebuttal is simply, I don't have enough time. So, given enough time, you could do it. Where's the evidence?
You have a fundamental misunderstanding of the process. Species are human classifications of different population groups as they change over time. However, species DO NOT turn into other species. It just doesn't happen! Population groups change over time. If we look back and take a snapshot every million years or so we may see large differences between various temporal snapshots of the population group. However, the population group is ALWAYS the same speicies...
In fact, for all we know a present day dog would not be able to breed with a dog that lived 25,000 years ago.
