Explanation: The Clovis tradition was practiced by a group of people who were some of the earliest settlers of the Americas. They used a stone technology known as flutes or points that were made from stones and attached to spears. These weapons were used to hunt large animals like mammoths. The culture flourished in the central plains and what is now the Eastern United states between 12,000 and 11,000 BP.

The people that practiced the Clovis tradition were once thought to be the earliest settlers in the Americas but recent archaeological evidence has shown that they are not.
