▶️ Watch on 3Speak

Describo información sobre la gran variación en tamaños y formas de los dientes premolares y molares de animales existentes y extintos, incluidos los homininos, con énfasis en los aspectos funcionales de las formas de los dientes. Destaco las posibles razones, consecuencias de la adaptación diente-dieta relacionada con la historia evolutiva y comento sobre la reducción del tamaño de los dientes en humanos.

I describe information on the great variation in sizes and shapes of premolar and molar teeth of extant and extinct animals, including hominins, with emphasis on the functional aspects of teeth shapes. I highlight possible reasons, consequences of dental-dietary adaptation related to evolutionary history and comment on the reduction of teeth size in humans.
