The Claim
The isotopic evidence from seven Australopithecus individuals at Sterkfontein is not representative of species-wide dietary patterns in Australopithecus or other early hominins due to geographic and temporal limitations and insufficient sample size.
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.
Dietary patterns inferred from the isotopic data of seven Australopithecus fossils from Sterkfontein cannot be assumed to apply to all Australopithecus or other early human ancestors because the sample is too small and comes from a limited time and place.
See the scientific wording
The isotopic evidence from seven Australopithecus individuals at Sterkfontein cannot be generalized to all Australopithecus populations or to other early hominins, as the sample is geographically and temporally restricted and too small to represent species-wide dietary patterns.
A small group of individuals lived in one place and ate mostly plants, so their teeth show a diet pattern that only reflects their local environment and food options, not what other groups far away or at different times ate.
What the research says
1 studyStudy: Australopithecus at Sterkfontein did not consume substantial mammalian meat.
This study looked at the teeth of just seven ancient ancestors in one place in South Africa and found they mostly ate plants, not meat. It doesn’t say all early humans ate the same way—just these few, so we can’t assume everyone else did too.
