This couple would represent the ancestors of the Native American peoples, who would have arrived in the Americas from northeastern Asia around 15,000 years ago (back then, Asia and North America were joined by a land bridge called Beringia which has since been submerged). The spears they are wielding have points based on those associated with the Clovis culture that spread across North America between 13,000 and 10,000 years ago. They would have used these to hunt big game such as mammoths, mastodons, and bison.
