      Late Pliocene and Early Pleistocene epochs 3.6 to 0.8 million years ago had climates resembling those forecasted under future warming. Palaeoclimatic records show strong polar amplification with mean annual temperatures of 11–19 °C above contemporary values. The biological communities inhabiting the Arctic during this time remain poorly known because fossils are rare. Here we report an ancient ...

      Analysis of ancient environmental DNA (eDNA) has revolutionized our ability to describe biological communities in space and time,1, 2, 3 by allowing for parallel sequencing of DNA from all trophic levels.4, 5, 6, 7, 8 However, because environmental samples contain sparse and fragmented data from multiple individuals, and often contain closely related species,9 the field of ancient eDNA has so far ...
