Investigating the roles of Hes and Sox genes during embryogenesis of the spider Parasteatoda tepidariorum
One goal of evolutionary developmental biology is to understand the mechanisms that underlie the regulation and evolution of embryogenesis among different species. One approach to answer these questions is to study and compare the expression and function of “toolbox” genes in different lineages. …

Appendage development and early Distal-less regulation in arthropods: A study of the chelicerate Tetranychus urticae (Acarida)
A major goal of evolutionary developmental biology is to explore mechanisms and events underlying evolution of the myriad body plan morphologies expressed both genetically and phenotypically within the animal kingdom. Arthropods exhibit an astounding array of morphological diversity both within and …

The Nurture of Nature: Biology, Psychology and Culture
… consequences taking development seriously in evolutionary considerations will have for how we understand the evolution of psychology and culture. I first explicate the relationship between development and evolution that informs a number of approaches to evolution, including neo-Darwinian …

Early land plant origins of the MYB-bHLH-WDR complex
A major aim in the field of evolutionary developmental biology (evo-devo) is to identify the mechanisms by which developmental novelties arise. The observation that incited the present study was the identification of a common theme across the differentiation of multiple specialised cell types in …

Comparative Physiological and Genomic Analyses of Division of Labor in Honey Bees and Paper Wasps
… of social behavior inspired by the field of evolutionary developmental biology (""evo-devo""); I suggest complex social behavior evolves via co-option of mechanisms underlying basic forms of solitary behavior, such as feeding and reproduction. Next, I describe research with honey bees (Apis …

Limbs gone batty : the role of the anterior-posterior patterning signal, Sonic Hedgehog, in the development of the unique bat limb
… a new and exciting model for the field of evolutionary developmental biology, which seeks to reveal the molecular mechanisms behind vertebrate limb diversity. The digits of the bat forelimb, excluding the thumb, are considerably elongated and webbed. The hindlimb digits are free of webbing …

Developmental Basis of Wing Pattern Diversity in Heliconius Butterflies
A major challenge to evolutionary developmental biology is to understand the how modifications to gene regulatory networks can lead to biological diversity. Heliconius butterfly wing patterns provide an excellent example of this diversity. In particular, the species H. melpomene and H. erato …

Colouration evo-devo: the developmental basis of intra-specific variation in cichlid pigmentation
… and how organisms diversify is a major goal of evolutionary biology. The fields of evolutionary developmental biology, evolutionary ecology, and population genetics have taken complementary approaches to this task, yet a lack of integration between these fields limits our understanding of the …

The evolution of somitogenesis: Mechanisms of paraxial mesoderm elongation in zebrafish and other vertebrates
In vertebrate embryos, a process called somitogenesis lays the foundations of the adult spine. This process involves elongation and segmentation of the paraxial mesoderm to form somites. Although the segmentation aspect of this has been widely studied, the elongation aspect is not well understood. …
