TL;DR: It is shown that DNA and amino acids from buried organisms can be recovered from the basal sections of deep ice cores, enabling reconstructions of past flora and fauna in high-altitude southern Greenland.

TL;DR: It is found that the toothed whales are monophyletic, suggesting that echolocation evolved only once early in that lineage some 36–34 Ma, and support is found for increased diversification rates during periods of pronounced physical restructuring of the oceans.

TL;DR: The results show evidence of bacterial survival in samples up to half a million years in age, making this the oldest independently authenticated DNA to date obtained from viable cells and find strong evidence that this long-term survival is closely tied to cellular metabolic activity and DNA repair that over time proves to be superior to dormancy as a mechanism in sustaining bacteria viability.

TL;DR: Recent molecular evidence suggests that crustaceans may have successfully invaded land as insects.

TL;DR: It remains doubtful whether amplifiable DNA sequences and viable bacteria can survive over geological timescales, so a rigorous set of authentication criteria is proposed for work with geologically ancient DNA.
