Explanation:

- Common Territory: Tribes typically have a distinct geographical area they identify with. This territory is crucial for their cultural and social activities.

- Sense of Unity: Tribal communities often have a strong sense of unity and belonging, fostering a communal lifestyle and shared goals.

- Exogamous Group: Tribes are generally endogamous, meaning that they prefer marriages within the tribe rather than outside it. Thus, an exogamous group is not a feature of a tribe.

- Common Language: A shared language helps tribes maintain communication and pass down traditions and customs.
