26 million animals are used every single year in the US for scientific, and commercial testing. Animals are usually used to develop medical treatments, determine the toxicity of certain medications, or any products meant for human use, or other biomedical, commercial, and health care uses. Testing on animals has been lasting from at least 500 BC.
Some good uses for animal testing that has come out to be good is that it had brought us development of many life-saving treatments for both animals and humans. There seems to be no alternative method for researching on a completely living organism.
Some may say that animal testing is cruel and that there shouldn't be a process like this for such animals. Again as if the moment there is no other alternative

it was also an instrumental in the development of pacemakers, cardiac valve substitutes, and anesthetics.
Chris Abee, director of the university of Texas M.D. Anderson Cancer Centers animal research facility, states that “we wouldn't have vaccines for hepatitis B without chimpanzees”. And also states; “ Finding a vaccine for hepatitis C, a disease that kills 15,000 Americans annually. If thalidomide had been properly tested on pregnant animals, its potential for causing severe birth defects would have been discovered before the drug became legal for human use.”.
Another pro is that animals are appropriate research subjects because there are similar to human beings in lots of ways. Chimpanzees share 99% of DNA with humans, and mice are 98% genetically similar to humans. Mammals and humans are from common ancestors, And have the same set of organs that function in most of the same way with the help of a bloodstream and central nervous system. Since animals and humans are so biologically similar, they are more susceptible of lots of the same conditions and illnesses, including cancer, diabetes, and heart
