Overview

Examines how head shape influences bite force in lizards, suggesting varying evolutionary pathways across scales.

Key Points

  • To explore how head shape and bite force correlate in lizards across multiple hierarchical levels.
  • Analyzed head shape using geometric morphometrics
  • Measured bite force in lacertid lizards
  • Examined relationships at individual, species, and family levels
  • Significant associations between head shape and bite force found at all levels
  • Body size influences the form-function relationship but is not the only factor
  • Evolutionary trajectories for the relationship varied randomly across scales
