Animals have been used repeatedly throughout the history of biometric research. In addition, early greek physicist scientists such as Aristotle and Erasistratus were no more different in 300 BC. In recent years the campaign to lessen the suffering of animals and avoid animal experimentation are trending, which shows two opposite type of mindset about people, one who feels bad for poor animals and others who think about the importance of such experiments. In my perspective, animal testing is ethically and morally wrong.
