Deskripsi
‘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 ecosystem composition between 13,500-10,000 years BP and persistence of some species past their supposed extinctions.’
