Mammalian dentition is characterized by heterodonty, in which both the upper and lower teeth are differentiated morphologically into four types: flat, chisel-shaped incisors, conical canines, bicuspid premolars and multicuspid molars in the mesiodistal direction.

Explanation:.

The mesiodistal crown:dimension is the smallest of any maxillary teeth.The mesiodistal measurement of the pulp chamber is wider compared to the labiopalatal one. The periphery of the socket often dips down palatally, labially, mesially and distally to accommodate the shape of the root. Maxillary central incisor:The general shape is similar to maxillary central incisor except that they are shorter and narrower. It has the most cervically located contact area of any incisor. The mesioincisal and distoincisal angles are more rounded than the corresponding angles of maxillary central incisor.Permanent mandibular central incisor:The crown dimensions are the smallest of any tooth, it has bilaterally symmetrical crown, and the line angles are the sharpest of any tooth.It shows the shallowest labial developmental grooves, smoothest lingual surface contour and the least developed cingulum.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records. some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
