@Kasz actually species is just a rather aribitrary thing. It doesn't need to be impossible for them to breed physically and produce fertile offspring, it just requires some barrier to reproduction.

In the case of wolves and dogs it's the fact that the wolves live in habitats that the dogs (even the wild dogs such as dingoes) do not occupy. Hence they don't breed and as such are different species.

The species classification has its uses but it also has its limitations and most of those are a heck of a lot of grey area.

Yeah... it's... stupid honestly if you ask me.

How can you take two animals that are indistinguishable in DNA tests and say they are different species?

Ahh, they aren't actually indistinguishable in their DNA. Just very similar. I'm not sure where you got that from, but I'm certain it's not true.

I've read in several sources that you can't tell wolves and various breeds of dogs by any DNA test including DNA fingerprinting.

You can trace family lines... but you can't really look at a DNA line and know exactly what it is like you could wike a monkey or some such.

Maybe there has been further refinment since i've read that though that i haven't come opon.
