Don't backpedal. Unless there is a mule population that is self sustaining this does not change the fact that genetic material from horses doesn't go into the stock of donkeys and vice versa.Blue-Lightning said:Horses and donkeys are not in the same species because there is no transfer of genetic material due to the infertile offspring.
That's the general rule... however there are exceptions. If you'll check the website I provided concerning mules and hinnies, you'll find that they are only usually sterile.
[quote:eea5e]Great Danes and Chihuahas are the same species because, while they can't reproduce directly, there is genetic flow from one to the other through other dog breeds.
But then that leaves the question of the jungle cats that can breed between species and why they aren't a single species understood to be different breeds instead of completely different species.

If you really want to argue on the taxonomy of jungle cats, you can go and scream your head off at a taxonomist. This doesn't change the fact that evolution happens and that isolated populations become more and more different from the rest of their species, to the point that they eventually become a new species. This can be shown to happen, it has happened. With long enough genetic isolation they can become a new genus, and further. And unless you're willing to make a sorites fallacy here, the debate is over.
[quote:eea5e]If creationism is to be credited with creating the seperate species at one point in time, then there should not be these "grey areas" of speciation. Each species should be clear and distinct from the others.
Of course, I don't believe in simple creationism, but I would respond by saying that perhaps there aren't gray areas. Perhaps each species is clear and distinct. Look at horses, zebras, and donkeys (to name a few)... why is it that we just accept that they are a different species? They can breed together and they would over time if humanity hadn't separated them for the most part through urbanization and destruction of habitat. Perhaps it is us who make gray areas in our minds...

I doubt horses from Persia would have migrated to Africa or to the Mongolian steppe for an equus bootycall.
[quote:eea5e]I think this current debate topic is a bit of a red herring.
Well, that's your opinion, but I used it to set up the future arguments that I have. And I think I've knocked enough holes in the idea that we have species classifications right that a few people may be more interested. Plus, its not a typical argument is it?
Now, I believe it is Tua's turn to start a topic. The debate would be severely one-sided if he were to get to respond twice to my statements and get the last word every time. So I will wait for the new topic Tua starts which should strengthen the argument for macroevolution.

I, too, am having problems with your argument in this area. I will look forward to seeing you put this into a more complete context. ON WITH THE FIRESTORM!!!
