FAMAGUSTA GAZETTE – A study published in Royal Society Open Science has revealed the role of diet and food preparation in the evolution of early human ancestors, particularly Homo habilis.
Unlike their robust australopith predecessors, Homo habilis had a jaw structure unable to generate strong molar bite forces, limiting their ability to process hard foods.
Researchers from the University of New England and East Tennessee State University found that early Homo species likely consumed softer, pre-processed foods to avoid stress on their jaw joints.
This shift reduced evolutionary pressures on jaw and tooth strength and marked a key dietary divergence from australopiths.
The study suggests dietary innovations, potentially aided by tools, may have begun with Homo habilis, not just Homo erectus as previously thought.
These changes, alongside food processing techniques, likely contributed to the emergence of modern humans.
