Aiming at analyzing the possibilities of approximation between the fields of biology and psychology, the article selects key concepts relevant to the understanding of the importance of contemporary biology. Firstly it presents some often neglected theoretical, methodological and epistemological questions involved in the approximation between psychology and biology. Afterwards, it describes a brief historical account of the developments of biology and some of their appropriations by other theoretical fields in the course of the Twentieth Century. After a brief presentation of the theoretical approximations already done between the fields, it suggests that this movement constitutes a first step towards an informed and interested interlocution between these two fields.
