Why is it helpful to study the external and internal structure of the rat?
Why study rat's internal and external structures? "For the pure sake of learning new things", could be one answer. We need to study external and internal structures of a rat in order to acquire correct knowledge about rats. Now for a selfish answer. Since human beings are so much like rats, when we know something more about rats, we nearly always have learned something about ourselves. More so in the past, but still today, we have less moral dilemna in doing testing on rats than on our fellow human beings. In other words, we are willing to cage them, perform experiments that cause irritation, great discomfort or death to a rat that we feel compelled not to when testing ideas with humans. We generally feel that it is immoral to give a human a condition and then to experiment with it. However, we generally don't feel that it is so immoral to give a rat a condition and then to subsequently try to experiment with it. The rat in this last context is a model of a human. what surprises most people is how good a model a rat has been to us. In other words, we are a lot like a rat.
