According to Kent, Ohio-A science news In the report, Kent State University’s Metin Eren and colleagues reviewed evidence collected at all 15 sites in North America where Clovis stone tools have been found along with the remains of mammoth, mastodon or gomphothere. “Archaeologists routinely believe that these localities provide evidence that Clovis people hunted these multi-ton animals, and this in turn provides evidence to support claims that humans had a role in the extinction of these large mammals,” Eren said. But the team’s review of the information could not rule out the possibility that Clovis people scavenged the carcasses of these animals. The microscopic wear patterns found on Clovis points may be caused by hunting, but can also be produced by cutting or dropping tools on the ground. Furthermore, no Clovis point or point fragment has been found in the bone of any one of these animals, Eren said. An earlier chemical study of the bones of the so-called “Anzic Child”, an infant who died during the Clovis period and was buried in what is now Montana, found that the child’s mother had eaten large amounts of meat. Eren and his colleagues argue that humans cannot digest this amount of protein. Rather, they suggest that the high levels of nitrogen in the infant’s bones may come from insects eaten by the mother, which have been shown to have high values of nitrogen, Eren explained. “Researchers cannot currently differentiate [hunting from scavenging] “It cannot be shown archaeologically and thus reliably how many Clovis proboscidean sites represent hunting versus scavenging events,” Eren concluded.
