Right, and even if they could produce, say a dog who had been mutated to the extent that it could constitute a new species, then they have to answer the question: “How would this ‘new’ species perpetuate itself?”
Obviously, if the mutations were not contained in the reproductive cells, then this “new” non-dog could still breed with regular dogs, and would produce a perfectly normal dog, not a member of the new species. If the mutations did occur in the reproductive cells, the animal would not be able to breed with any dogs and the new species would die along with it.
The only possible way the evolutionists can overcome this obstacle, that I can fathom, is if by some miraculous confluence, all of the exact same genetic mutations were passed down to at least one male and one female offspring, and by another miraculous confluence, this male and female of the “new species” were located near enough to each other geographically that they would find each other and mate, and by a third miraculous confluence, the resulting offspring were able to survive long enough to establish this new species securely in the biosphere. Oh, and these extremely improbable events would have to repeat themselves at least 10’s of thousands of times, for every instance of speciation postulated for sexually-reproducing animals.
Keep in mind, all of these improbabilities must be piled on top of the preceding mountain of improbabilities that would have to be surmounted in order for “random genetic mutations” to accumulate to the point of producing a chain of beneficial (or at least neutral) adaptations that would lead to the production of the member of this “new” species in the first place. All of which the Darwinists believe as an act of faith, since these events are not observable, replicable, or falsifiable.
Do me a favor, read a little about Mendel's (a priest, by the way) laws of inheritance. http://en.wikipedia.org/wiki/Mendelian_inheritance More generally: No offense intended, but there is certain ignorance with respect to science on our side of the political spectrum. This allows the Left, for example, to peddle all the garbage about global warming. All kinds of crap, which should make a scientist cringe, are presented to the public with impunity, in part because we allow them to do this...
