Which mathematics should be learned for biology?

A viewpoint on the teaching of mathematics in biology is presented. It is based on a definition of the notion of the living organism, a description of an integrated didactic space where a curriculum is a path in this space, and, finally, a proposal for a framework of teaching extending from the bachelor's degree to the doctorate and taking into account the students' objective, either scientific or engineering. The aim of these reflections is to trigger a discussion on the presentation of programmes for the teaching of mathematics in biology curricula, making it possible to establish the objectives to be achieved from bachelor to master.
