Evolutionary Theory in the 21st Century: Towards a New Unification of the Life Sciences?
Eva Jablonka
“Evolutionary theory is the most general framework for understanding the biological world. It is a conceptual bottleneck through which any theory of life and mind must pass. If a biological (or psychological, or sociological) theory fails to pass through this bottleneck, it is likely there is something seriously wrong with it.” (Ginsburg and Jablonka 2019, pp. ix-x)
Evolutionary theory, which, as the quote above suggests, is the most integrative and general framework within the life sciences, has been evolving since the early 19th century, when it was first clearly articulated. Combining historical, sociological and philosophical considerations, alongside new findings and models in the life sciences, the course will provide an overall view of the current, 21st century development-informed state of the theory, as well as the challenges and debates surrounding it. We shall start with a historical and philosophical-theoretical overview of evolutionary theorizing, discussing major biological concepts such as function, teleology and self-organization, and outlining the history of evolutionary ideas from the 19th century until the end of the 20th century. Current ideas and studies that extend and challenge 20th century neo-Darwinian dominant views of evolution, will then be surveyed.
The interconnected topics the course will focus on will be:
- Introduction: The history and philosophy of evolutionary theory; 19th century ideas, neo-Darwinism, 20th century “Modern Synthesis”, and current debates. Major organizing concepts and their transformations (2 meetings).
- Developmental plasticity and canalization, developmental biases and developmental affordances. (1.5 meetings)
- Inclusive inheritance (i.e., genetic, epigenetic, behavioral, and symbol-based inheritance). (1.5 meetings)
- Niche construction and organismal agency
- The porous and evolving boundaries of biological individuality
- Phylogenetic and ontogenetic selection processes; patterns of relations in the biological world
- Different types of major transitions during the history of life: ecological, informational and teleological
- Learning and evolution. The evolution of learning, learning as evolution, and evolution as a learning process
- The evolution of consciousness (of subjective experiencing)
- Cognitive approaches to morphogenetic development; basal cognition; the implications of the cognitive view for theorizing about evolvability and innovation
- Developmental systems-theory inspired ways of representing and modeling biological, social-ecological systems in the Anthropocene
- Is there a paradigm shift in evolutionary theorizing today? Does current evolutionary theorizing offer a new framework for the unification of the life sciences? How can changes in evolutionary theorizing affect currently emerging disciplines and how can new technologies affect evolution and evolutionary theorizing?
