“…The inadequacy of the developmental constraint concept to grasp the creative nature of development has been criticized several times by people close to the constraints school (Gould, '89;Arthur, 2002Arthur, , 2003Richardson and Chipman, 2003). The alternatives proposed, bias and positive constraint, still fail to describe development.…”

“…These authors claimed that all morphologic changes in evolution imply changes in development and that development can produce, at any given time, only a limited number of morphological variants. This implies that development does strongly influence evolution (Alberch, '80, '82;Oster and Alberch, '81;Kauffman, '83;Wagner, '88;Antonovics and van Tienderen, '91;Wagner and Misof, '93;Resnik, '95;Schwenk, '95;Hall, '96;Schlichting and Pigliucci, '98;Arthur, 2001Arthur, , 2002Fusco, 2001;Richardson and Chipman, 2003). This is often stated as development constraining or limiting the evolutionary process.…”

“…Then, as suggested by the constraints school, significant insights about the evolution of morphology can be obtained by studying specific developmental mechanisms and how they produce morphologic variation. A large number of studies specifically consider pattern formation in evolution (Alberch,'80 Goodwin, '94;Sanders, '94;Newman and Müller, 2000;Arthur, 2001Arthur, , 2002Richardson and Chipman, 2003). These identify aspects of the variational properties produced by a partially known developmental mechanism.…”

“…The basic ensemble of concepts used to approach evolution and development in most current research is borrowed either from the neo-Darwinian synthesis or from a set of theoretical works from the early eighties appearing as, more development based, alternatives to some neo-Darwinian assumptions (here loosely referred as the constraint school: Alberch, '80, '82;Oster and Alberch, '81;Stearns, '82;Wake et al, '83;Wagner, '88;Horder, '89;Wake, '91;Wagner and Misof, '93;Arthur, 2001Arthur, , 2002Richardson and Chipman, 2003). A long-lasting controversy between these two approaches is whether development constrains the direction of evolution or, on the contrary, selection is the only main player in determining the direction of evolution.…”

Developmental constraints vs. variational properties: how pattern formation can help to understand evolution and development

This article suggests that apparent disagreements between the concept of developmental constraints and neo-Darwinian views on morphological evolution can disappear by using a different conceptualization of the interplay between development and selection. A theoretical framework based on current evolutionary and developmental biology and the concepts of variational properties, developmental patterns and developmental mechanisms is presented. In contrast with existing paradigms, the approach in this article is specifically developed to compare developmental mechanisms by the morphological variation they produce and the way in which their functioning can change due to genetic variation. A developmental mechanism is a gene network, which is able to produce patterns in space though the regulation of some cell behaviour (like signalling, mitosis, apoptosis, adhesion, etc.). The variational properties of a developmental mechanism are all the pattern transformations produced under different initial and environmental conditions or IS-mutations. IS-mutations are DNA changes that affect how two genes in a network interact, while T-mutations are mutations that affect the topology of the network itself. This article explains how this new framework allows predictions not only about how pattern formation affects variation, and thus phenotypic evolution, but also about how development evolves by replacement between pattern formation mechanisms. This article presents testable inferences about the evolution of the structure of development and the phenotype under different selective pressures. That is what kind of pattern formation mechanisms, in which relative temporal order, and which kind of phenotypic changes, are expected to be found in development.

“…Thus, redeployment of the same set of genes can also arguably serve to increase the morphological diversity in primates, vertebrates and metazoans. It has been argued that interaction between developmental bias and natural selection determines evolutionary direction of particular body plans [36].…”

How organismal complexity is achieved is a fundamental biological issue. The surprising revelation that complex eukaryotes have fewer than expected genes presents an important challenge for deciphering how organisms achieve complexity. The genome size and the gene number do not necessarily correlate in a consistent manner with the perceived organismal complexity. In this review, we focus on known molecular mechanisms that increase genetic complexity at the molecular and functional levels, and discuss features that have likely contributed to organismal complexity.

A Trait‐based framework for mutation bias as a driver of long‐term evolutionary trends

Previous work has shown that mutation bias can direct evolutionary trends in genotypic space under strong selection and rare mutation. We present an extension of this work to general traits of the organism. We do this by allowing many different genotypes, with different fitnesses, to have the same trait value. This approach makes novel predictions and shows that the outcome of evolution for a trait is influenced by mutation bias as well as the fitness distribution of the genotypes that have the same trait value. This distribution can alter evolution in interesting ways, depending on the likelihood of generating high fitness mutants. We also show that mutation bias can direct evolution when many mutants are present at any one time. We demonstrate that mutation bias can drive longterm evolutionary trends when the environment is constantly changing. Under biologically realistic conditions, we show that mutation bias can counter strong gradients of environmental selection over time. We conclude that evolutionary trends can be quite independent of the environment, even when they depress population fitness. Finally, we show that entropy can be a powerful source of mutation bias and can drive evolutionary trends. V C 2015 Wiley Periodicals, Inc.
