Thanks To The New Technology
Fortunately, the new technology revealed sequencing that went back further in time than ever before. “Now, the analysis of ancient proteins with mass spectrometry, an approach popularly known as palaeoproteomics, allows us to circumvent these restrictions,” Cappellini said. And in this case, a sample of enamel provided the right opportunity.
The Discovery Is An Exciting Milestone
Despite this, the project took a decade to complete. Jesper Velgaard Olsen, a co-author of the paper, worked with Cappellini to meticulously retrieve the material they needed from the ancient teeth. “This discovery is an exciting milestone in palaeoproteomics,” Olsen said simply.
