Animal testing

Animal testing

The experimentation on animals increased, especially the practice of vivisection, so did criticism and controversy. In 1655, the advocate of Galenic physiology Edmund o'Meara said that "the miserable torture of vivisection places the body in an unnatural state." Others argued that animal physiology could be affected by pain during vivisection, rendering results unreliable. There were also objections on an ethical basis, contending that the benefit to humans did not justify the harm to animals.Many people believed that animals were inferior to humans and so different that results from animals could not be applied to humans.
On the other side of the debate, those in favor of animal testing held that experiments on animals were necessary to advance medical and biological knowledge.

Animals are also used foreducation and training; are bred for use in laboratories; and are used by the military to develop weapons, vaccines, battlefield surgical techniques, and defensive clothing.For example, in 2008 the United States used live pigs to study the effects of improsive explosive devices explosions on internal organs, especially the brain.
In the US military,goats are commonly used to train combact medics (Goats have become the main animal species used for this purpose after the Pentagon phased out using dogs for medical training in the 1980s.) While modern mannequins  used in medical training are quite efficient in simulating the behavior of a human body, trainees feel that "the goat exercise provides a sense of urgency that only real life trauma can provide".
