Abstract
Abstract
The post-genomic era raises questions about neo-Darwinian genetic determinism. Instead, open aspects of macroevolution become intelligible by Evo-Devo research. At all developmental levels, self-organization acts robustly towards “wholeness”, as exemplified by organoid technologies. In retinal reaggregates histotypical features are reached along different formative routes. Thus, tissue formation is not merely gene-directed, but channeled by unpredictable external conditions. These insights restrict conceptions of onto- and phylogenesis. Neither is characterized by unlimited randomness nor by finite genocentrism. A re-examination of Driesch’s drive to wholeness, i.e., robustness and intentionality, appears timely, while his teleologic postulates remain undecidable by reductionist reasoning.
