New Study Reveals Complex Evolution of Saber-Toothed Tigers

Research uncovers nuanced cranial forms and accelerated evolutionary rates in saber-toothed species, offering insights into their rise and decline.

Scientists used 3D scanners to analyze 99 mandibles and 91 skulls from various species and eras.
Results show a continuum of cranial forms linking modern cats and saber-toothed counterparts.
Saber-toothed species exhibited faster morphological evolution early in their history.
Reduced craniomandibular integration in these species allowed for greater adaptability.
Specialized niches made saber-toothed predators more vulnerable to extinction.
