New paper about the functioning of saber teeth led by the amazing @TIPollock 🥳 combining 3DGM with biomechanical testing we identified functional optimality as a key driver underpinning the repeated evolution of extreme saber-tooth morphologies 🔪🦁 cell.com/current-biology/ful…

Sabre teeth are a classic example of convergence. Our new study, integrating 3D shape, biomechanics, and optimality modelling, helps explain why: revealing that functional optimality was a key driver behind the repeated evolution of extreme sabre-tooth morphologies🔪🦷 Link⬇️
