What Scientists Learn from Animal Experiments

A scientist was studying reaction responses in frogs.  He took a frog and put it on the floor.  The floor was marked off in feet and inches.  Standing behind the frog, the scientist clapped his hands and shouted loudly.  The startled frog jumped about 4.5 feet.  The frog was retrieved and sedated.  

The scientist proceeded to remove one of the frog’s front legs, cauterizing the incision, and then left the frog to recover.  A few days later, the scientist repeated the experiment, noting that this time, the frog jumped about 4 feet.

Over the next several days, the surgery, recovery, test cycle continued with the scientist noting the decreasing distance the frog jumped after each amputation.  Eventually, the frog has no legs.  

The scientist puts the frog down at the starting point, claps his hands, and shouts loudly.  The frog doesn’t budge.  The scientist repeats his actions with the same result.  The legless frog is just sitting there.  

The scientist picks up his test log and makes the following entry:  “Frogs with no legs are deaf.”
