Overview

This study demonstrates how evolutionary constraints shape craniofacial morphology in Madagascar primates, indicating adaptive responses across different sizes.

Key Points

  • Smaller lemurs exhibit limited cranial shape diversity due to evolutionary constraints that impact their morphology.
  • Dwarf/mouse lemurs and sportive lemurs maintain a similar cranial shape yet adapt through distinct modifications to specific cranial parts.
  • Larger taxa like Megaladapis show diverse cranial morphologies, reflecting fewer constraints and suggesting novel skull functions.
  • Even in the context of evolutionary constraints, craniofacial diversity can arise by channeling adaptations based on body size.
