FishFreak95;4287874; said:Ive calmed down and most of what you said I agree with except about dog breeds. All dog breeds are the same species unless crossed with a dingo or wolf or other related species. All dog breeds are a result of selective breeding.
If you were to talk about being the same species. Depends on how deep you want to dig back into the history. Selective breeding, isn't that considered as hybrid? Hybrid is pretty much just 2 different breed/species crossed with one another and therefore just cross more into it to create something that you wanted. So let's say you cross about 10 different species of dog and created the perfect dog that you wanted it. Now if these 10 dogs were crossed and created about 500 of the off spring that you wanted it, this might cut the line between hybrid and pure wouldn't it? As I have stated before, population will cut the end the between hybrid and pure. Selective breeding is just crossing different species into on how you wanted it to be. Select which is right for what type of job to be done. Now selective breeding between bloodlines of the dog is a whole different story now. Let's talk about the infamous pitbull here, let's say we cross a colby with a chinaman. It would not be considered as hybrid due to the fact that most part of its gene is still the same. Just that the dog working potential is different from one another. Now selecting breeding with certain breed such as the manchester and german shepard plus other breeds out there to create a doberman. That is still considered as a hybrid, but do to population and popularity of the dog. The term "hybrid" has been cut out from that dog. Now you can just mix a doberman with a doberman and you get a doberman. When you can do that, this plays a big role of considering it a hybrid of pure.
Also remember that Dingo is a hybrid, they escaped into the wild and now have populated in Australia. This is why they are now called pure. But truth, they aren't pure. Same goes for human, scientist believe that the 1st human or most ancient human came from Africa. And we all descend and spread into our own in differentiation into different countries. As different genes inside of us appear, we all change the way how our physical traits is. But this is something scientist believe till today, but it is still not 100% fact and proven.
