Evolutionary explanation and bucket thinking

The hierarchical interplay between ecology and genealogy is a fundamental ingredient for the most compelling current explanations in evolutionary biology. Yet philosophy of biology has hardly welcomed a classic fundamental intuition by palaeontologist Niles Eldredge, i.e. the non-coincidence and interrelation between ecology and genealogy, and their interaction in a Sloshing Bucket fashion. Hierarchy Theory and […]

The hierarchy theory view of speciation

Hierarchy theory (e.g. Salthe 1985, Eldredge 1986) provides a unifying approach for representing the multi-level structure of the organic world and an explanatory framework for the wide range of natural phenomena. Its birthdate can be located in the 1980s, when evolutionary biologists began exploring in detail the nature of hierarchical systems as an approach to […]

Criticizing adaptive landscapes, ecology and genealogy

Disentangling ecological vs. genealogical dimensions is a core task of hierarchy theory in evolutionary biology. As Eldredge repeatedly epitomized, organisms carry out (only) two distinct kinds of activities: they survive, and they reproduce. At the organismal level, the organism stays the same whether we consider it ecologically or genealogically – yet, differences can occur in […]

Master Degree Dissertation in Educational Sciences, University of Milano Bicocca, Milan, Italy. [DOI 10.13140/2.1.3863.5525] This is an epistemological research, concerning knowledge processes. The choice of African Cichlids as a subject has been stimulated mainly by the fact that these fishes […]
