Final answer:

The evolution of dentition in hominins is characterized by small jaws and teeth, a larger third molar, a skull shape resembling Homo erectus or Homo habilis, bipedal locomotion with a human gait, and human-like feet with arches and ankles.

Step-by-step explanation:

The evolution of dentition in hominins has several distinctive features. One key characteristic is the presence of small jaws and teeth, along with a larger third molar compared to other molars. Hominin skulls also have a skull shape similar to Homo erectus or Homo habilis, with a sagittal keel, a small raised ridge on top of the skull.

Furthermore, hominins display bipedal locomotion with a human gait and have human-like feet with arches and ankles. These adaptations in dentition and locomotion are important markers of evolutionary changes in the hominid lineage.
