The evolution of fast movements: new paper published in the journal Evolution

Postdoc Thomas Claverie, UC Berkeley undergraduate Eliot Chan, and Sheila Patek published a new paper in the journal Evolution. This paper offers a new look at the evolution of systems that generate extremely fast movements.  Using cutting edge methods to analyze biological shape, the authors examined how the components of the power amplification system in mantis shrimp vary relative to each other during development.  They found that the "spring", "engine" and "tool" are developmentally modular, suggesting evolutionary lability in the development and evolution of power-amplified systems.  Understanding the extent to which these components are coupled or uncoupled has important implications for the diversification of power amplification systems and the geometric morphometrics analyses open up new avenues for comparative studies of fast biological movements.
