Ancient environmental DNA and environmental archaeology
Ancient environmental DNA(ancient eDNA)refers to ancient DNA(aDNA)derived from palaeoenvironmental samples. Different from ancient DNA, ancient eDNA contains a mixture of highly fragmented DNA from multiple organisms, and usually attached to humic acids and mineral particles. Ancient eDNA has been f...

Ancient environmental DNA(ancient eDNA)refers to ancient DNA(aDNA)derived from palaeoenvironmental samples.

Ancient eDNA technology started in 1998, and has experienced three stages of development:(1)identifying specific species through DNA barcodes, (2)recovery of certain groups of organisms via DNA metabarcoding, and (3) reconstruction of paleoecosystems using shotgun metagenomics.
