Ground squirrel droppings, preserved for millennia in the Yukon's deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed genetic information about an environment that no longer exists. It is among the oldest ancient DNA ever recovered and sequenced.
