Evolution of dogs

[JTsyo]

Will the different breeds of dogs eventually stop being able to interbreed? Already there are purebreds that are kept separate from the other breeds, though mutts tend to be healthier. But with humans creating artificial selection I don't think evolutionary fitness means much.

Probably not. It's unlikely that one breed of dog is going to remain completely isolated from all other dog breeds for the tens of thousands of years it would take for speciation to occur.

considering wolves can still breed perfectly fine with domesticated dogs I'd say it's so far down the road some event will probably wipe out all life on the planet before it happens.

Its just a theory, not a proven fact.

fitness is contextual.

Dogs are extremely fit in that we humans go "awwww it's so cute!" and then provide food, water and opportunities to reproduce.

That sounds acceptable. When we get rid of puggles you go right along with them.

Technically some breeds of dogs can not viably self sustain. I think French & English bulldogs for example have reached a point where the heads of the animals are physically impossible to pass through the birth canal and require C-sections to get the pups out. Handpicking traits for designer animals isn't healthy.

I assume you're trolling. In science, evolution is considered as factual as gravity.

Anyway, if a very large breed male breeds to a very small breed female, the female would likely die due to the inability to give birth to very large puppies. If the large breed female breeds with the very small breed male - well, it's actually funny to watch the poor male trying and getting frustrated - they don't succeed.

Not trolling but sarcastic.

You see this shit all the time in the dog world.

I don't think he's trolling, I think he may be hiking somewhere down in Texas.

Yeah, you're right. Reality is that Jesus loved puppies, so He created dogs. It's in the Bible, look it up. You can't deny God's truth.

You must not read many of the evolution threads.
