PLEASE READ CAREFULLY
(here are at least 15 examples):

and since evolution proceeds by the accumulation of many small scale changes,
if there were no barrier to these small changes, you would expect the changes to give an incredible diversity of living organisms (the way the fossil record shows).
So, what barrier to constant change do you propose?

Fireball: I'm just trying to get an answer to a reasonable question. Why don't you try?

Question:
Creationists may call those examples of subspeciation, but they would be dead wrong. Those are examples of new species that are not compatible with others.
Tell me, with these almost 20 genera of canids mentioned, represented by over 100 species, where do you draw the line for what you call a dog?:

And actually, Great Danes and Chihuahuas can interbreed, (they just do not normally do so). But that is a good point for how reproductive isolation begins. First you have the physical difficulty, then the genetic impossibility. Perhaps sometime in the future, they will become different species (just imagine if some carnivore came along that eliminated all medium sized dogs - the large ones may be too big, and the small ones may be good at hiding). That is how incipient speciation works.

Also Question, notice that the article you've provided gives no mechanism.
