This chapter reviews traditional and newer approaches to the empirical study of biological form, highlighting the contribution of experimental evolution to an improved understanding of why and how particular transformations in animal shape occur. It begins by reviewing different mathematical methods for quantifying and comparing organismal shape, focusing on one methodology in particular: the scaling relationship between two traits. The chapter also examines the biology of shape expression and evolution, and presents case studies where experimental evolution has been used to explore various aspects of scaling relationship evolution.

Keywords:   biological form, experimental evolution, animal shape, shape expression
