Natural Selection in Ernst Haeckel’s Legacynisms corresponded to those in Darwin’s own theory. In this chapter, we will examine this issue and demonstrate that although Haeckel championed natural selection throughout his whole career, his neo-Lamarckian concept of variation made his grasp of natural selection different from that of Darwin.

Recasting Natural Selection: Osborn and the Pluralistic View of Lifeoften minimized. This chapter aims at exploring the research program in evolutionary biology that Osborn outlined between the 1910s and the 1920s. I will consider in particular how Osborn aimed at overcoming the specialization of biological studies through a renewed holistic approach in life science

Fourth, it was unlikely that the timing of reproductive isolation would make adaptive evolution possible. Fifth, the selection-balance controversy exposed a variety of additional reasons for doubts about the role of selection. This skepticism a
