The evolutionary loss of morphological traits is often driven by changes in gene regulation. Many developmental genes are controlled by multiple, redundant enhancers, raising the question of how robus...

Novelty, Co-option and Divergence During Gene Network Evolution Recent studies on the evolution of novel traits provide a window of opportunity to understand how existing gene-regulatory networks (GRN...

Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Whole genome duplication (WGD) generates new genetic material that can contribute to the evolution of the regulation of developmental processes and phenotypic diversification. A WGD occurred in an anc...

Abstract. Sexual conflict can drive the divergence of male and female phenotypes and cross-species comparative analyses have documented patterns of correla

Oxford Brookes partners with leading institutions to train the next generation of researchers addressing global challenges in life and environmental sciences.

In Lepidoptera (butterflies and moths), the genomic region around the gene cortex is a “hotspot” locus, repeatedly implicated in generating intraspecific melanic wing color polymorphisms across 100 mi...

Regulatory mapping at a developmental gene reveals an unexpected architecture of entangled, rather than modular, enhancers.

Abstract. The prevalence and diversity of female ornaments pose a challenge to evolutionary theory because males should prefer mates that spend resources o

Insect male genitalia are among the fastest evolving structures of animals. Studying these changes among closely related species represents a powerful approach to dissect developmental processes and g...

The process of sexual development in animals is modulated by a variety of mechanisms. Some species respond to environmental cues, while, in others, sex determination is thought to be controlled by a s...

Behavioral mating choices and mating success are important factors in the development of reproductiv

Understanding how genetic variation impacts transcription factor (TF) binding remains a major challe

Our understanding of how cis-regulatory elements work has advanced rapidly, outpacing our evolutionary models. In this review, we consider the implica…

Abstract The role of visual search during bee foraging is relatively understudied compared to the choices made by bees. As bees learn about rewards, we predicted that visual search would be modified t...

Ridgway et al. show that the transcription factor Sox21b represses the size of the posterior lobes of male Drosophila genitalia. Sox21b expression differs during posterior lobe development between D....
