article_snippet: Researchers at Oxford University found the evidence trapped inside human teeth discovered in the rainforests of Sabaragamuwa in southern Sri Lanka (pictured) Researchers at Oxford University say isotopes in human teeth discovered in the rainforests of Sabaragamuwa in southern Sri Lanka suggest the people Researchers at Oxford University belonged to had a diet mainly composed of food foraged from the forest.
article_snippet: The researchers, whose work is published in the journal Science, studied the fossilised teeth of 26 humans of a range of dates - from 20,000 to 3,000 years ago - found around Sri Lanka.
article_snippet: By examining the carbon and oxygen isotopes in the teeth, The researchers, whose work is published in the journal Science were able to see that the humans had a diet that matched those of people living in slightly open 'intermediate rainforest' environments.
article_snippet: the fossilised teeth of 26 humans of a range of dates - from 20,000 to 3,000 years ago - found around Sri Lanka were found in rainforests  in southern Sri Lanka including in the Batadombealena cave (marked) Patrick Roberts, an archaeology student at Oxford University and lead author of the study, said: 'This is the first study to directly test how much early human forest foragers depended on the rainforest for how much early human forest foragers diet. '
