In this connection, the differentiation of mammalian teeth took place, what are their functions?

Differentiation of teeth arose due to the varied nature of the food that the animals ate. Depending on the nature of the food, animals have developed certain types of teeth. Incisors, the function of which to cut food, are more developed in herbivores. In predators, the incisors are shorter, but the canines are much more developed, because they tear off pieces of meat with them. In herbivores, molars are more pronounced for chewing food. In humans, as an omnivore, the teeth are expressed in approximately the same way.
