What is Man that You are Mindful of Him? 

Genetics & Human Nature in the Gaze of  Jérôme Lejeune

An investigation into “human nature” from the witness of Jérôme Lejeune, doctor and discoverer of trisomy 21, pioneer of clinical genetics, and strenuous defender of human life. 

The extraordinary development of genetics has opened great possibilities and expectations, but has also brought to the fore the question: “Do we want to know in order to cure or to select?” The most recent discoveries in evolutionary biology make it quite difficult to think of living beings, and most of all of man, as totally determined by genes. Thus an idea very dear to Jérôme Lejeune resurfaces: that every man is “unique” and “irreplaceable,” and should be seen as such.
