The traces of genetic material that humans constantly shed wherever they go could soon be used to track individual people, or even whole ethnic groups, scientists said on Monday, warning of a looming “ethical quagmire.”
A recently developed technique can glean a huge amount of information from tiny samples of genetic material called environmental DNA, or eDNA, that humans and animals leave behind everywhere — including in the air.
The tool could lead to a range of medical and scientific advances, and could even help track down criminals, according to the authors of a new study published in the journal Nature Ecology & Evolution.
In a time of both misinformation and too much information, quality journalism is more crucial than ever.
