Great, now put the two together and you get what I've saying all along. A "group" that has been mating and sharing their genes and evolving, sooner or later they have produce a change in the number of chromosomes or else today, every living thing would have the same number of chromosomes, which they don't. Now it would seem, in the world around us, a differing number of chromosomes seems to be a rather large hindrance to reproduction. This is based on....what? A large portion of our genes don't do anything, not to mention that differing number of chromosomes tend to prevent species from mating that shouldn't (not that they were designed to prevent that mind you). Genes change over time, certain qualities are preferred, others get left behind as junk quote:
Now what I have been saying is; no matter how much a "group" has mated and evolved, when that change in the number of chromosomes happens, a new "group" has to be formed because they can no longer mate with the "group" that evolved them. Great, that is what Evolution says happens and as far as I know there is no scientific evidence that shows that could not have happened. Um, no, that isn't what evolution says can't happen. You'll find several species of birds that can mate with each other. Lets do a though experiment to explain it, as I remember learning back in highschool. Species A is the original species of seagull, Species B is an offshoot of species A which formed over several thousand years, Species C is a Species that offshoots from Species B, D from C, and E from D. These species all exist at the same time, Species A can still mate with Species B because there isn't a vast amount of variation between them. The same with B and C, C and D, and D and E. A->B->C->D->E However, because the changes between A and E are so much larger, they cannot reproduce successfully. They have undergone too many changes in their genetics to remain compatible. What are the changes? Well you might as well be asking me to tell you the name of the sperms who died trying to fertilize your mothers egg. Again, it is a thought experiment that has already established evolution as truth, but explains why species are no longer compatible between each other. A real life example with humans would be neandertals, with which we have mated with and there is evidence of Neandertal DNA mixed into the Homosapien species. They are/were the closest relative we had and we were able to mate with them. However, we wouldn't have been able to mate with homo-erectus if it had been around with us, because the change in genetics between us and them would have been too big. Do you understand what I'm saying? Closely related species can reproduce, but species that are much further apart can't. quote:
But being some what pragmatic, I have to ask; do I really believe that over the millions of times that happened, Evolution managed to produce at least a male and a female of that new "group" at the same time and place, every time? And as GotSteel was so kind to point out, one pair is not a viable start to a new "group" and so Evolution would have produce more than just two, each time. Perhaps that seems credible to you but to me it seems to be pushing credulity and would seem to take blind faith to believe. ;-) Jesus man, you still don't understand evolution one bit. Evolution didn't manage to produce one male and female to create a new group. Evolution is slow and gradual, never abrupt. It's hard to figure out when species change, but it does happen and it happens over a long period of time. When a species is forced into a new environment, natural selection either kills off the species because it doesn't survive, or some of the species endures and is able to adapt, slowly selecting for traits which allow the species to survive and continue reproducing. Over time, the species that survives will no longer resemble their ancestors, because their ancestors didn't have the same qualities needed to survive they way their descendants do. Do you understand gradual? And do you understand how long millions of years is? It's a long time, time enough for small changes to turn into big changes, big changes which resulted in new species.
