Jesse T. Hughes, Melissa E. Williams, Mark Rebeiz, Thomas M. Williams https://doi.org/10.1002/jez.b.23068 Abstract Changes in gene expression are a prominent feature of morphological evolution. These changes occur to hierarchical gene regulatory networks (GRNs) of transcription factor genes that regulate the … Continue reading →

However, understanding … Continue reading →

One primary agenda of the developmental evolution field is to elucidate molecular mechanisms governing differences in animal form. While mounting evidence has established an important role for mutations in transcription controlling cis-regulatory elements (CREs), the underlying mechanisms that translate these … Continue reading →
