Abstract in brief
Saber-tooth canines are a prime example of convergent evolution, appearing multiple times in mammalian history due to their specialized predatory advantages.
There is a trade-off in the shape of canine teeth between improving food fracture and maintaining tooth strength, with optimal shapes balancing these needs.
Research shows that extreme saber-tooth shapes are functionally optimal, enhancing puncture performance even at the cost of breakage resistance, highlighting the significance of functional adaptation in their evolution.
