Hasn t every major medical advance been attributable to experiments on animals?
Medical historians have shown that improved nutrition, sanitation and other behavioural and environmental factors not anything learned from animal experiments are responsible for the decline in deaths since 1900 from the most common infectious diseases and that medicine has had little to do with increased life expectancy. Many of the most important advances in health are attributable to human studies, among them anaesthesia; bacteriology; germ theory; the stethoscope; morphine; radium; penicillin; artificial respiration; antiseptics; the CAT, MRI and PET scans; the discovery of the relationships between cholesterol and heart disease and between smoking and cancer; the development of x-rays and the isolation of the virus that causes AIDS. Animal testing played no role in these and many other developments.
