Smoker,
Way back in beginning biology, we are taught to analyze all angles of a problem/situation/question and only use empirical evidence to form our conclusions. This is the nature of biology. We cannot use conjecture or hearsay to form a conclusion, otherwise we would quickly become laughing stocks of the scientific community.
For example, if you were to go to the doctor and say, "doc, I get dizzy and short of breath easily, and just yesterday my arm wouldn't move very well", I bet everything I own he wouldn't say, "hey, I hear there's a bug going around, it's nothing, go home and take a nap and you'll be fine". The doctor would immediately form a hypothesis in his mind of what may be your problem, then he would draw blood, listen to your heart and maybe even hook you up to an elektrocardiogram. All to prove his hypothesis. That's how he was trained. Form and opinion the go about proving or disproving your opinion.
Your coydog question was easy. It's already been proven. You guessed it, by emperical evidence.
Now, if you were to tell me you believe in the tooth fairy, and swore up and down they exist, I probably wouldn't debate the issue with you. I also wouldn't listen to you long. On the other hand, if you told me you had evidence the tooth fairy existed, I would look at the evidence myself and form my own opinion. If the evidence was conclusive, I would publish a paper for all of my peers to review. They would form their own conclusion and if the evidence withstood their efforts to debunk our evidence, you and I would be famous for discovering the tooth fairy!!! /ubbthreads/images/graemlins/grinning-smiley-003.gif /ubbthreads/images/graemlins/grin.gif
That's the nature of the biological world. /ubbthreads/images/graemlins/grinning-smiley-006.gif
