Summary:

The documentary "Three Identical Strangers" made by British filmmaker Tim Wardle (2018) and translated into Spanish as "Separate lives" comes to us as one more product to be consumed from the Netflix platform. It gives us different testimonies and opens up bioethical problems that are interesting for its treatment and debate. In this writing I will deploy four axes of problematization around the documentary: a) research and experimentation with human beings; b) the right to identity of adopted children; c) the natural nurture debate that today is strongly developed in the field of natural sciences regarding epigenetics and d) the debate on kinship relationships in boys and girls born by donation of gametes who seek to meet their genetic siblings.

Key words: bioethics in research | genetics and epigenetics | right to identity
