The beginning of life of a new human being from the scientifi c biological perspective and its bioethical implications

Abstract

The issue of when the human life begins is a very important subject since it has a signifi cant impact on the decisions that we have to take in relation to human beings in development, particularly human embryos. In this article we discuss some of the more relevant biological evidence supporting the fact that beginning human life begins unquestionably at fertilization and the bioethical consequences.
