There is no doubt that the best test species for humans are humans. It is not possible to extrapolate animal data directly to humans due to interspecies variation in anatomy, physiology and biochemistry.
Advancing in science is important. It is what helps us understand the world in which we live, and is especially important for medical research. However, some believe the myth that, in order to effectively continue our research, we must experiment on animals. This is not the case at all and, in fact, can give us inconclusive results. Here are just a few of the alternatives that are not only cruelty-free, but many of these produce more accurate results:
-In vitro (test tube) test methods and models based on human cell and tissue cultures
-Computerized patient-drug databases and virtual drug trials
-Computer models and simulations
-Stem cell and genetic testing methods
-Non-invasive imaging techniques such as MRIs and CT Scans
