upvote, with the disclaimer that science also acknowledges that some experiments are non-repeatable either in theory or practice.
So when that animal dies the experiment cannot be repeated and the research is pretty much over until they find another smart animal to work with.
So many of these animal experiments are very non-repeatable both in theory and in practice.
And btw, while I'll accept the point in theory, do you have any realistic examples of unrepeatable experiments in mind? Besides ones involving people, I guess.
