Abstract

This paper attempts to reconcile the conceptual conflict between typological and population thinking to provide a philosophical foundation for extended evolutionary synthesis (EES). Typological thinking has been considered a pre-Darwinian, essentialist dogma incompatible with population thinking, which is the core notion of Darwinism. More recent philosophical and historical studies suggest that a non-essentialist form of typology (i.e., representational typology) has some advantages in the study of evolutionary biology. However, even if we adopt such an epistemological interpretation of typological thinking, there still remains an epistemological and methodological conflict between these two styles of thinking. How can we relate typological thinking with population thinking in pursuit of more integrated or interconnected research into evolutionary biology? I propose that homology thinking, which is another style of thinking that recognizes homologous characters, provides a common basis for typological representations of character states and for character dynamics in an evolving population. Good examples of this bridging role are found in teratology and breeding, where variation and novelty are recognized in developmental and morphological traits, gene expression patterns, and so on. Essentialism-free, dynamic views of homology have great potential to reconcile typological and population thinking and to set the stage for the EES.

Notes

  1. Here “the gap is bridged” does not mean that the gap is completely filled or closed but that the two areas separated by the gap can be interrelated, although the gap remains.

  2. Note that these “grounds” do not necessarily provide certain criteria for the identification of homologs. We can recognize homologs, even if neither their historical continuity nor developmental mechanism is clear. See Remane (1952) for the most prominent operational criteria of homology (summarized in Griffiths 2007, p. 648).

  3. It is notable that Simpson (1944, p. 98) argued that “the paleontologist has more reason to believe in a qualitative distinction between macro-evolution and mega-evolution than in one between micro-evolution and macro-evolution.”.

  4. For other problems of this theory in the context of homology, see Suzuki and Tanaka (2017).

  5. The relationship and compatibility between PRM and causal model views is worthy of further discussion. As this issue strays from the main topic in the current paper, however, it is left for future work.

  6. The processual philosophy of biology (Dupré and Nicholson 2018) is an ontological theory that has some affinity to a dynamic view of homology. According to the PRM view, for example, homologs are considered neither members of a natural kind nor parts of an individual but as subprocesses (each homolog) of a process (homologs as a whole) that exhibit coherence (modularity of each homolog) and persistence (persistent reproductivity of homologs). For a detailed discussion of coherence and persistence of biological processes, see DiFrisco (2018). Also, dispositionalism in the processual philosophy of biology might provide a better framework for understanding causation in biology, ontologically, and epistemically (Anjum and Mumford 2018).
