You can go from one breed of dog to another.
How do you know when you've gone from one breed of dog to another?
You evolutionists are all wasting time.
Is that so? I guess I'd better pass the word around, here in the lab. "Hey, everybody! Pack it up! I know you were getting some great results but we're done; some 14-year-old kid on the internet has informed us that we're all wasting our time."
Might I suggest, oh, I don't know, an actual
education before you attempt to assess what fields of scientific inquiry are liable to be fruitful? Just a thought.
