Final answer:
Patrilineal descent is known among most North Americans and the Ju/'hoansi of the Kalahari Desert.
Step-by-step explanation:
The form of descent known among most North Americans and the Ju/'hoansi of the Kalahari Desert is patrilineal descent. In patrilineal societies, descent is traced through the father's line, and children typically assume their father's last name. This is similar to the practice in the United States, where most children assume their father's last name even if the mother retains her birth name.
