This paper tackles some of the ethical considerations related to the broad question of bioethics. Throughout the research, the assumption is made that bioethics is founded on clear philosophical and theoretical foundations and that discussions of bioethical questions can be informed by ontological, metaphysical and ethical bases. This allows the researcher to investigate these visions by revealing what the author terms “Meta-Bioethics” or “Metaphysical Bioethics”. The paper concerns itself with the philosophical interpretation of the human relationship with evolution in biotechnologies and the physical nature of man. It is concerned also with the ontological and ethical status of biotechnological development, and the associated problems, which are referred to or implied by the present-day philosophical debate.
