Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). Due to degradation processes (including cross-linking...

cloning DNA directly from environmental samples as early as 1985. This led to the first report of isolating and cloning bulk DNA from an environmental sample...

Bølling–Allerød warming, which likely disrupted its habitat, with environmental DNA records possibly extending the range of the species around 9,800 years...

up the free nucleotides these nucleases generate from environmental DNA. The energetics of DNA uptake are not understood in any system, so it is difficult...
