Evolution is scientifically unproveable
I think dogs are the best example of this. I don't claim to be an expert but hear it out and just refute where you like...
Dogs evolved from wolves.
The breeding of dogs are acceleration of the evolution process. Instead of natural seleciton, you have man acting as the selector. Those he accepts are nurtured and bred again until he is satisfied. Now we have hundreds of breeds for various purposes. But here's the key thing, because dogs quickly evolved from wolves to be tameable, dogs have tied themselves to the hip with men. As a species, it found a host to nurture it and continue its existence. Dogs cannot survive in the wild but why does it need to now when men is the environment? So, I don't see dogs becoming extinct until men becomes extinct.
