How should evo-devo be carried out?
There is no standard procedure for conducting evo-devo. Nevertheless, numerous conventional steps are involved, as well as feature of development and function useful in a phylogenetic context, the collection of trait-controlling applicant genes and the developmental functions verification.
The principle of evo–devo in morphology as it affects genetics
The real beauty of evo-devo is the functional confirmation of candidate genes and the ability to reveal how these genes control traits in organisms via reverse genetics mediated by organisms’ transformation. Zhang et al. (2010) stated that a particular feature achieved by manipulating trait-determining genes, specifically synthesis in a non-trait close relative is crucial evidence. The selective values of the feature can be inferred accordingly and further verified experimentally. Evo-devo has focused on the evolution of the genetic mechanism of development. Rapid improvement in the cloning of regulatory genes and new techniques of visualising gene expression in embryonic tissues has made this the most valuable part of experiential evo-devo at present.. The discovery of extensive similarities in gene regulation between distantly related species with essentially different body structures…
