Final answer:
Pre-Clovis and Clovis sites are connected with the hunting of large prehistoric animals like mammoths and mastodons. Clovis sites are distinguished by the unique 'Clovis points' used as hunting tools, while pre-Clovis artifacts suggest a broader range of subsistence strategies including hunting, gathering, and fishing.
Step-by-step explanation:
Pre-Clovis and Clovis sites are primarily associated with the hunting of various megafauna that existed during the Paleo-Indian period. Among the prey for the Clovis people were mammoths, mastodons, giant bison, and other large animals. The Clovis culture is well-known for its distinctively crafted Clovis points, which were used to hunt these big game animals. Meanwhile, evidence from pre-Clovis sites such as the Monte Verde in Chile suggests an earlier human presence in the Americas, with a subsistence strategy that included hunting, gathering, and fishing, indicated by a broader array of tools and practices, prior to the widespread adoption of the Clovis technology.
