Abstract
Population control through discriminatory practices is found at all times in history. Never before, however, has use of the sciences been so close to achieving the creation of new mechanisms for generating human "subspecies". This study, which is based on a selected theoretical framework, deals with the biotechnological and bioethical challenges on the path to manipulation as concerns the development of potentially harmful practices in a pluralist context. Segregation or even the destruction of undesirable human beings is a frightening reflection of an egocentric and largely prejudiced society. However, the future will not necessarily be obscure if Homo sapiens can act ethically and positively.
