Phylogeny & Evolution of Organismal Design

Research on organismal biomechanics can illuminate the transformation of animal design through time, and help explain the mechanical design of organisms.


Theoretical approach (from Lauder, 1981) to studying the transformation of design in organisms. This approach considers both the transformation of design and the historical effects of innovations early in the evolution clade.
