“…Also, some authors have hypothesized that the patterns of genetic and developmental modularity should evolve to match the patterns of functional modularity [399,419,[425][426][427]. Clearly, this "matching hypothesis" [428] provides a rationale for investigating the relation between modularity of fluctuating asymmetry, which indicates the developmental basis of modularity, and modularity among individuals or genotypes. If a hypothesis of modularity is available, based on functional, anatomical or developmental considerations [72,178,179,428], it can be tested using geometric morphometrics [170].…”

Analyzing Fluctuating Asymmetry with Geometric Morphometrics: Concepts, Methods, and Applications

Approximately two decades after the first pioneering analyses, the study of shape asymmetry with the methods of geometric morphometrics has matured and is a burgeoning field. New technology for data collection and new methods and software for analysis are widely available and have led to numerous applications in plants and animals, including humans. This review summarizes the concepts and morphometric methods for studying asymmetry of shape and size. After a summary of mathematical and biological concepts of symmetry and asymmetry, a section follows that explains the methods of geometric morphometrics and how they can be used to analyze asymmetry of biological structures. Geometric morphometric analyses not only tell how much asymmetry there is, but also provide information about the patterns of covariation in the structure under study. Such patterns of covariation in fluctuating asymmetry can provide valuable insight about the developmental basis of morphological integration, and have become important tools for evolutionary developmental biology. The genetic basis of fluctuating asymmetry has been studied from empirical and theoretical viewpoints, but serious challenges remain in this area. There are many promising areas for further research that are only little explored at present.

“…Several authors have called for and attempted to outline an extended evolutionary synthesis (EES) [3][4][5][6][7] , and most researchers who agree that such a synthesis is necessary regard evo-devo [8][9][10][11][12][13] as providing the major impetus for it; after all, one of the elements that is missing from the original synthesis is an integrated account of development. In particular, the EES must explicitly account for the evolution of phenotypic novelties [14][15][16] that are explained only in general terms by the Modern Synthesis.…”

Is evolvability evolvable?

2008

| In recent years, biologists have increasingly been asking whether the ability to evolve -the evolvability -of biological systems, itself evolves, and whether this phenomenon is the result of natural selection or a by-product of other evolutionary processes. The concept of evolvability, and the increasing theoretical and empirical literature that refers to it, may constitute one of several pillars on which an extended evolutionary synthesis will take shape during the next few years, although much work remains to be done on how evolvability comes about.

“…Rather, something is a module to the extent to which it can change independently in evolution. Modularity is not just due to an organism's structural arrangement, but due to its functional-developmental organization, where a module's partial dissociation results from the larger developmental context in which it figures (Breuker et al 2006;Gonzalez et al 2011;Jamniczky and Hallgrímsson 2011). The different body segments of segmented animals are structurally distinct and can evolve independently, but many developmental pathways are involved in the formation of all segments.…”

Evolutionary Developmental Biology and the Limits of Philosophical Accounts of Mechanistic Explanation

Evolutionary developmental biology (evo-devo) is considered a 'mechanistic science,' in that it causally explains morphological evolution in terms of changes in developmental mechanisms. Evo-devo is also an interdisciplinary and integrative approach, as its explanations use contributions from many fields and pertain to different levels of organismal organization. Philosophical accounts of mechanistic explanation are currently highly prominent, and have been particularly able to capture the integrative nature of multifield and multilevel explanations. However, I argue that evo-devo demonstrates the need for a broadened philosophical conception of mechanisms and mechanistic explanation.Mechanistic explanation (in terms of the qualitative interactions of the structural parts of a whole) has been developed as an alternative to the traditional idea of explanation as derivation from laws or quantitative principles. Against the picture promoted by Carl Craver, that mathematical models describe but usually do not explain, my discussion of cases from the strand of evo-devo which is concerned with developmental processes points to qualitative phenomena where quantitative mathematical models are an indispensable part of the explanation. While philosophical accounts have focused on the actual organization and operation of mechanisms, properties of developmental mechanisms that are about how a mechanism reacts to modifications are of major evolutionary significance, including robustness, phenotypic plasticity, and modularity. A philosophical conception of mechanisms is needed that takes into account quantitative changes, transient entities and the generation of novel types of entities, feedback loops and complex interaction networks, emergent properties, and, in particular, functional-dynamical aspects of mechanisms, including functional (as opposed to structural) organization and distributed, system-wide phenomena. I conclude with general remarks on philosophical accounts of explanation.
