Introduction
Mechanical performance of biological structures is deter-
mined by interactions between their intrinsic material
properties, larger scale morphologies, and behavioural
utilization. Many studies link interspecific differences in
performance with variation in morphology or physiology
(Bennett & Huey, 1990; Losos, 1990a; Garland & Losos,
1994). However, few systems allow for reliable charac-
terization of both intrinsic and macro-scale properties of
structures in relation to organism performance (Madrell,
1998). Hence, we lack a broad understanding of
the pathways by which natural selection modifies
material properties in conjunction with morphology
and behaviour.
The intrinsic properties of many biomaterials appear
relatively fixed across large clades, which could reflect
