6. Toulmin’s Model of Reasoning Grounds (Evidence) Claims Qualifier Rebuttal Warrant Jaffe, p. 361

8. Animal research is beneficial to humans. Animal research has increased the overall health of the human race because of new medicines and surgical procedures made possible through animal experimentation.

9. Animal experimentation has given us cures for polio and provided the necessary knowledge to treat diabetics with insulin.

10. Without animal testing we would not have chemotherapy for cancer patients and those suffering from HIV would not have medicine to help control the progression of the disease (from The Americans for Medical Progress.)

11. So, because of animal experimentation, we have invented medicines and surgeries that help polio, diabetes, cancer and HIV patients.

12. Obviously, animal experimentation has not cured these diseases, but it has provided us with medicines like insulin and procedures like chemotherapy that help the suffering of human beings.

13. There are those who say that animal testing is cruel and ethically wrong, but Americans for Medical Progress as well as a study in The New York Times stated that both human AND animal health has been helped through animal experimentation.
