A study titled "Functional optimality underpins the repeated evolution of the extreme 'saber-tooth' morphology" published in Current Biology reveals why: these teeth were 'functionally optimal ...

In the history of teeth, perhaps no tooth is as famous as the saber tooth. These long, blade-like canines seem almost perfectly optimized to kill prey. They've evolved at least five times in mammals, ...
