The dental system of mammals differs from other vertebrates in a number of features. Name at least three features.

Differences between the teeth of mammals and the teeth of other chordates:

1. Teeth have roots.

2. Milk teeth change to permanent with age.

3. Teeth are differentiated, that is, they are divided according to their functions: incisors – serve for biting off food; canines – protection and capture of food, indigenous – grinding food.

Among the representatives of the predatory order, a special predatory tooth stands out among the molars. It is distinguished by its particularly sharp edges and serves for biting off, since their incisors are small. With their help, they gnaw bones.
