He said archaeologists analysed very ancient tissue samples to see the ratios of carbon and nitrogen to determine diet composition and change.
“A high level of nitrogen might suggest a diet that is rich in animal protein, while a lower ratio could predominantly be a plant-based diet,” he said.
This technique allows researchers to bridge the gap between scientific analysis and historical context, building connections to individuals who lived centuries ago.
“This is an important thing that allows us to use science to piece together this historical context that we might find human remains.”
