ABSTRACT
The history of biology might really close with the establishing of the dissolution of Darwinism. This theory undeniably constitutes a construction of thought of its own, and the ideas and methods of research that have succeeded it are still in the developing stage, and their possibilities of development can at best be only guessed at. A summary glance at these conquests of the newest biology is nevertheless defensible as a further justification for the defeat of the old ideas and in view of the intrinsic interest that the new discoveries possess. The author, who himself laboured exclusively in the sphere of the old morphology and who accordingly does not feel justified in competing with the many splendid presentations of the development of experimental biology that already exist, proposes to make only very brief reference to the results of modern research and give a short account of the theoretical reflections to which they have given and may give rise.
