Traditionally, it has been supposed that the central object of Biology are 'organisms'. The expression "organism" is relatively recent in the use that it has nowadays -it was introduced by the authors of the German Idealism- but corresponds to a very traditional notion. An 'organism' is a substance composed by a plurality of materials organized by the same substance that acts upon itself to persist in time, in order to a finality that is the organism itself. To make intelligible an organism seems indispensable its order to an end. This teleological perspective, nevertheless, is unacceptable for the reductivist perspective of Biology, prevalent since the triumph of what has been called the "Modern Synthesis" the first half of last century. It has been proposed, for that reason, to substitute the traditional idea of 'organism' by that of 'Darwinian individual' (cf. Godfrey-Smith, 2009), that could offer a more adequate perspective of the object of Biology. The object of this science could not be organisms, but individuals that can enter the Darwinian evolutionary drift. In this work it is explained why a hiatus persists between organisms teleologically oriented and a Darwinian individual. The Darwinian perspective leaves aside the central character of the object of Biology: life.
