“We have to observe the complex interactions of cells, tissues, and organs in living animals.”
Taking a healthy being from a completely different species, artificially inducing a condition that he or she would never normally contract, keeping him or her in an unnatural and distressful environment, and trying to apply the results to naturally occurring diseases in human beings is dubious at best. ,Physiological reactions to drugs vary enormously from species to species. Penicillin kills guinea pigs but is inactive in rabbits; aspirin kills cats and causes birth defects in rats, mice, guinea pigs, dogs, and monkeys; and morphine, a depressant in humans, stimulates goats, cats, and horses. Further, animals in laboratories typically display behavior indicating extreme psychological distress, and experimenters acknowledge that the use of these stressed-out animals jeopardizes the validity of the data produced.
Sir Alexander Fleming, who discovered penicillin, remarked, “How fortunate we didn’t have these animal tests in the 1940s, for penicillin would probably have never been granted a license, and probably the whole field of antibiotics might never have been realized.”Modern non-animal research methods are faster, cheaper and more relevant to humans than cruel and irrelevant animal tests.
