The Claim
Low isotopic variability among humans at the Selivanovsky II burial ground is associated with a culturally standardized diet, regardless of genetic relatedness or mobility differences.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People buried at the Selivanovsky II site ate the same types of food, even if they were not genetically related or had moved from different places.
See the scientific wording
The low isotopic variability among humans at the Selivanovsky II burial ground, despite genetic and mobility differences, suggests a shared, culturally standardized diet among members of this kin-based group, even for individuals who were not genetically related.
People in this group ate the same kinds of meat and dairy throughout their lives, no matter where they were born or who their family was. Their bones recorded this same diet because the proteins from their food were broken down and rebuilt into bone tissue in the same way, making their chemical fingerprints match.
What the research says
1 studyEven though some people buried here weren't related and may have come from far away, their bones showed they all ate the same kinds of meat and dairy, suggesting the group had strong rules about what to eat.
