The Claim
Dental calculus from a 1.2-million-year-old hominin fossil contained plant fibers that may have been introduced through raw material processing rather than dietary consumption.
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.
Plant fibers found in ancient hominin dental calculus might have come from processing materials like plants for tools or other non-food uses, rather than from eating them.
See the scientific wording
Dental calculus from a 1.2-million-year-old hominin fossil contained plant fibers that may have been introduced through raw material processing rather than dietary consumption.
Plant fibers got stuck in the teeth not because they were eaten, but because the person used their mouth to handle or clean plant materials, like stripping bark or chewing on fibers to soften them for making tools.
What the research says
1 studyScientists found plant fibers in an ancient hominin's teeth and think they might have gotten there not from eating plants, but from using plants to make tools or clean their teeth.
