SUMMARY:Deep time proteins: an eggcellent resource for reconstructing past
  human-environment interactions - Beatrice Demarchi\, University of Turin

DESCRIPTION:Protein sequences preserved in the fossil record encode geneti
 c information which\, in some instances\, can survive approximately ten ti
 mes longer than DNA under the same conditions. As a consequence\, the new 
 discipline of palaeoproteomics (the study of ancient proteins\nby mass spe
 ctrometry) is currently having a tremendous impact on the study of the pas
 t\, allowing us to address open questions in archaeology and palaeontology
  over unprecedented timescales\, encompassing the whole of the Pleistocene
  and beyond.\nHere I discuss the role of deep-time proteins from non-conve
 ntional substrates\, such as avian eggshell\, in reconstructing past human
 -environment interactions. Focussing on the hotly debated issue of the ear
 ly anthropic impact on natural landscapes\, I tell the story\nof how ancie
 nt proteins helped us resolve a long-standing mystery involving giant exti
 nct flightless birds\, the first inhabitants of Australia\, and the leftov
 ers of cooked eggs.
