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.

该项目旨在了解胚胎中不同的肌肉群是如何形成的，以及如何在脊椎动物的胚胎发育中进化的。除了头部的肌肉外，所有的肌肉都起源于一种暂时的胚胎结构，称为皮肌节。从皮肌节的肌肉的形成使用一个高度保守的机制，这是从硬骨鱼和两栖动物部署不同。皮肌节是如何进化产生我们在脊椎动物的整个发育过程中所看到的不同类型的运动系统的，这一点仍然没有得到解决。这个项目的目的是有助于了解如何部署在重要的进化过渡不同的运动策略产生。
