Eco-geographic adaptations in the human ribcage throughout a 3D geometric morphometric approach
[Objectives]: According to eco‐geographic rules, humans from high latitude areas present larger and wider trunks than their low‐latitude areas counterparts. This issue has been traditionally addressed on the pelvis but information on the thorax is largely lacking. We test whether ribcages are larger...
