The Claim
Starch granules from grasses in the Triticeae or Bromideae tribe preserved in dental calculus of a 1.2-million-year-old hominin specimen were intact and undamaged, indicating that these plant foods were consumed in their raw, unprocessed state without cooking or mechanical grinding.
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.
Analysis of ancient dental plaque from a hominin fossil dated to 1.2 million years ago revealed undamaged starch granules from wild grasses, suggesting these plants were eaten raw and not cooked or ground.
See the scientific wording
Starch granules from grasses in the Triticeae or Bromideae tribe found in dental calculus of a 1.2-million-year-old hominin were intact and undamaged, indicating these foods were consumed raw without cooking or grinding.
When people eat raw grass seeds, the hard outer coating of the starch grains stays intact because no heat or chewing breaks them down. These undamaged grains get stuck in the teeth and stay preserved over time, leaving a clear sign that the food was eaten without cooking or grinding.
What the research says
1 studyScientists found tiny starch bits in an ancient hominin’s teeth that looked exactly like they would if eaten raw — no signs of being cooked or mashed. This means the hominin probably ate these grasses just as they grew, without cooking or grinding.
