Environmental DNA or eDNA is DNA that is collected from a variety of environmental samples such as soil , seawater, or even air. [1] rather than from an individual organism. Feces, mucus, gametes, shed skin, carcasses and hair are all sources of eDNA. [2] Such samples can be analyzed by high-throughput DNA sequencing methods for rapid measurement and monitoring of biodiversity. The analysis of such samples is called metagenomics.
