Reviews and Critique of the Theory of evolution in the Field of Normative Ethics

Evolutionary ethics in the normative field concerns the impact of evolutionary biology on the content of normative facts and the obligations based on these facts. The aim of current research is to consider the impact of evolutionary biology in the realm of normative ethics and is an attempt to answer this question: can biological factors influence the realm of moral obligations? The present research, at first reviews, with an descriptive - analytic approach, the anthropological theory of evolution which is based on the theory of evolution and its various applications in the field of ethics, and after that offers a detailed description of evolutionary normative ethics, followed by evaluating and critiquing it.
The results of the research show that evolutionary ethics can be categorized, like any other research, into subcategories, here as three branches of the descriptive, normative and meta-analyzed moral (which is often neglected in the study of evolutionary ethics), and assuming the correctness of the theory of evolution without the denial of its impact which is limited in the field of normative ethics, it is proved that a moral obligation has the necessity in relation to something else. Analogically, and because the need is real, the moral obligation has an objective reality. The source of these obligations does not lie in evolutionary factors, but in human reason and human perceptions in that there lie the mandate of human will and human power of choice.
