The project seeks to understand how different muscle populations within the embryo form and have evolved within the vertebrate phylogeny. All amniote muscles, except that of the head, derive from a transient embryonic structure termed the dermomyotome. The formation of muscle from the dermomyotome of amniotes uses a highly conserved mechanism that is distinct from that deployed by bony fish and amphibians. How the dermomyotome evolved to generate the distinct types of locomotor systems we see deployed throughout the vertebrate phylogeny remains unresolved. This project aims to contribute to an understanding of how different locomotor strategies deployed at important evolutionary transitions were generated.

该项目试图了解胚胎形式中不同的肌肉种群如何在脊椎动物系统发育中进化。除头部外，所有羊膜肌肉均来自瞬态胚胎结构，称为皮肤肌肌。羊膜皮肤肌肉的肌肉形成使用了一种高度保守的机制，该机制与骨鱼和两栖动物部署的机制不同。皮肤病组如何进化以产生我们看到在整个脊椎动物系统发育中部署的不同类型的运动系统类型。该项目的目的是为了理解如何在重要的进化过渡中部署的不同运动策略。
