THE EVOLUTIONARY DEVELOPMENT OF CROWN GALLOANSERAE SKULLS: TRACKING CHANGES IN GALLIFORM AND ANSERIFORM CRANIAL DEVELOPMENT
One of the most remarkable features of the animal kingdom is its diversity of forms in it, which has allowed animals to thrive in a wide range of niches throughout their evolutionary history. Understanding the origins of disparity remains one of the major goals of evolutionary biology. Of the …

How to build a chordate: Multiscale decomposition of axial morphogenesis in the amphioxus, Branchiostoma lanceolatum
All members of the chordate phylum are united by a shared body plan – a stereotypical composition and topology of tissues that emerges in the wake of gastrulation and defines the major anatomical patterns emerging in later development. For this reason, although there is remarkable anatomical …

Ancient origins of the chordate forebrain: Conserved patterning of the anterior neuroectoderm in amphioxus
While the general organization of the chordate central nervous system (CNS) is highly conserved and consists of a dorsal neural tube with an anterior brain, the evolutionary origin of this key aspect of the chordate body plan remains obscure. In recent years, a conserved anterior gene regulatory …

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 …
