This study seeks to define the ethics required today in order to  constrain evolutionary biological thought with normative constants, especially in an era where ethics is forced to oppose  the concept of progress. The objective of this study is to search for an answer to the question: How can ethics perform the work of an observer and guide, despite suffering from a foundational crisis due to its relationship with various cultural and religious influences? Relying on the analytical method, this study will specifically address the ethical philosophical arguments about current biological techniques, starting from the notion of  moral obligation together with what it entails for biological practice. The philosophical goal is  to prove the danger of Scientism, and the legitimacy of concern about biological research.
