Reconstructive evolutionary morphology: Tracing the historical process of modifications of complex systems driven by natural selection through changing ecological conditions

Published 2024 in Journal of morphology

ABSTRACT

There is general consensus among evolutionary biologists that natural selection drives phenotypic modifications within populations over generational time. How to reconstruct this historical process, however, has been discussed mostly in theoretical terms, and recommendations and explanations on how to translate such theoretical insights into practice are needed. The present study aims at providing a theory‐supported practical guide on how to reconstruct historical evolutionary processes by applying a morphology‐centered approach through a series of interdependent steps of descriptive morphology, functional analysis, ecological observation, integration of paleoecological data, and evolutionary synthesis. Special attention is given to the development of tests regarding the accuracy, closeness to reality, and plausibility of the hypotheses at every level of the reconstructive process. This morphology‐centered approach had its beginnings in the wake of the evolutionary synthesis and is part of the scientifically necessary process of reciprocal testing of hypotheses generated by different methods and data for the reconstruction of evolutionary history.
