Logically, saying that A caused B in one experiment is less valid than saying A caused B as different researches came to the same conclusion. To conclude, one single experiment is not enough to create a theory. Valid results are key. This cannot be proven in one shot. Peter Singer asserts that humans who promote animal research are in a sense “species-ists,” meaning that we tolerate cruelties inflicted on members of other species that would outrage us if performed on members of our own species. In this sense it would make as much sense to perform experiments on brain-damaged human beings then on animals. Essentially, animals have equal, or at least close to equal rights as humans do.
