“…Furthermore, in the specific case of skeletal developmental sequences, the first objective is to estimate accurately the timing of developmental events. From our perspective, this is the very first step prior further evolutionary analyses such as developmental sequence polymorphism (Colbert and Rowe, 2008), patterns of modularity (Poe, 2004;Goswami, 2007), or analyses of sequence heterochrony (Jeffery et al, 2005;Goswami, 2007;Harrison and Larsson, 2008). An environmental component to developmental studies should be integrated only after patterns of stability and variation have been assessed.…”

Background: Through developmental and evolutionary time, organisms respond variably to their environment not only in terms of size and shape but also in terms of timing. Developmental plasticity can potentially act on various aspects of the timing of developmental events (i.e., appearance, cessation, duration, sequence). In this study, we address the developmental plasticity of median fin endoskeleton by using exercise training on newly‐hatched Arctic charr (Salvelinus alpinus). Results: Developmental progress of cartilage formation (i.e., chondrification) in all fins is less influenced than ossification by an increase of water velocity. The most responsive elements, meaning those elements with greater onset plasticity owing to a water velocity increase, differ in terms of early versus late developmental events. The most responsive elements are those that chondrify and to a greater extent ossify later in the development. Conclusions: Plasticity is documented for the timing of appearance (i.e., onset) and the timing of transition from cartilage to bone (i.e., transitions of skeletal states) rather than the order of events within a sequence. Similarities of plastic response in developmental patterns could be used as a powerful criterion to strengthen the identification of phenotypic modules.

“…But it is not possible to "simply" identify stages between species for which the state of the development is identical: organs do not develop at the same speed and with the same sequence, development is heterochronous (e.g. [11]). …”

Abstract. Gene expression patterns are a key feature in understanding gene function, notably in development. Comparing gene expression patterns between animals is a major step in the study of gene function as well as of animal evolution. It also provides a link between genes and phenotypes. Thus we have developed Bgee, a database designed to compare expression patterns between animals, by implementing ontologies describing anatomies and developmental stages of species, and then designing homology relationships between anatomies and comparison criteria between developmental stages. To define homology relationships between anatomical features we have developed the software Homolonto, which uses a modified ontology alignment approach to propose homology relationships between ontologies. Bgee then uses these aligned ontologies, onto which heterogeneous expression data types are mapped. These already include microarrays and ESTs. Bgee is available at

“…In addition to contributing to a revisitation of homologies, evo-devo can contribute original data to the reconstruction of phylogeny, especially through a comparative analysis of sequence heterochrony (e.g., Velhagen, 1997;Smith, 2001;Bininda-Emonds et al, 2002;Jeffery et al, 2005;Minelli et al, 2007). This approach deserves strong additional effort, especially in plants, where its potential is still virtually unexploited.…”
