LOPEZ-MORATALLA, Natalia. THE ZYGOTE OF OUR SPECIES IS THE HUMAN. pers.bioét. [online]. 2010, vol.14, n.2, pp.120-140. ISSN 0123-3122.

This article clearly shows science offers us direct and indisputable knowledge about the beginning of human life. It tells us when we are in the presence of a human body in the temporal processes involving the transmission of life. It also gives us direct information about the personal nature of the embryo through the continuity of its development. The decisive fact is not that there is an uninterrupted sequence from the start; that is, from the early embryonic and fetal stages and birth, but that this continuity assumes the continuity of a body, which is always personal. Science offers us indirect knowledge about the origin of each human being, showing it has a human body and every human body has a trait exclusive to man: that of being a person. Science definitely demonstrates the presence of a real power, one that is different from the living force and is involved in the origin of each human being. The intertwining of biological and personal dimensions in the life of every man is a clear sign that every human being exists as one subject with two dynamisms: a personal being that is human in nature.

Keywords : Ser; person; human nature; human body.
