Each of these is commonly thought to derive directly from Clovis, in some cases apparently differing only in the length of the fluting on their projectile points. Post-Clovis cultures include the Folsom tradition, Gainey, Suwannee-Simpson, Plainview- Goshen, Cumberland, and Redstone. The Clovis culture was replaced by several more localized regional cultures from the time of the Younger Dryas cold climate period onward, about 12,000 years ago. The results of these analyses reveal that Anzick-1 is closely related to modern Native American populations, which lends support to the Beringia hypothesis for the peopling of the Americas.
Researchers from the United States and Europe conducted paleogenetic research on Anzick-1's ancient nuclear, mitochondrial, and Y-chromosome DNA. The only human burial that has been directly associated with tools from the Clovis culture included the remains of an infant boy named Anzick-1. Clovis people are considered to be the ancestors of most of the indigenous cultures of the Americas. Archaeologists' most precise determinations at present suggest that this radiocarbon age is equal to roughly 13,200 to 12,900 calendar years ago. The Clovis culture appears around 11,500–11,000 uncal RCYBP ( uncalibrated radiocarbon years before present), at the end of the last glacial period, and is characterized by the manufacture of " Clovis points" and distinctive bone and ivory tools. The Clovis culture is a prehistoric Paleo-Indian culture, named after distinct stone tools found at sites near Clovis, New Mexico, in the 1920s and 1930s. A Clovis projectile point created using bifacial percussion flaking (that is, each face is flaked on both edges alternately with a percussor)
