Phenotypic variation is the raw material for evolutionary diversification and adaptation. However, a critical gap remains in evolutionary theory be...

Nature Communications - The developmental hourglass has long been seen at the level of embryos. By zooming in to single cells, this Perspective shows that mid-embryonic conservation arises from...

Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeli...

Rates of phenotypic evolution vary across traits, and these evolutionary patterns themselves evolve. Understanding how development contributes to s...

This work used the model EmbryoMaker to explore the most basic set of morphologies that can be produced from spherical initial conditions by activating cell properties and behaviors in simple genetic...

Corn snakes are a useful model organism for studying skin pigmentation. Here they characterize the Terrazzo morph and identify the role of PMEL in the patterning of pigmented cells in the skin, explai...
