Cold Spring Harbor Perspectives in Biology, 2013 Under favorable conditions DNA can survive for thousands of years in the remains of dead organisms. The DNA extracted from such remains is invariably degraded to a small average size by processes that at least partly involve depurination. It also contains large amounts of deaminated cytosine residues that are accumulated toward the ends of the ...

Collapse of the mammoth-steppe in central Yukon as revealed by ancient environmental DNA
Nature Communications, 2021 ‘The timing and ecological dynamics of extinction in the late Pleistocene are not well understood. Here, the authors use sediment ancient DNA from permafrost cores to reconstruct the paleoecology of the central Yukon, finding a substantial turnover in ...
