Beneath the frozen Yukon, the humble droppings of ancient ground squirrels have preserved a genetic chronicle spanning 700,000 years — a reminder that the most unassuming remnants of life can carry the deepest memory. Researchers from McMaster University, the Hakai Institute, and the University of Alberta have recovered DNA from over 200 plant species and iconic megafauna like woolly mammoths, reconstructing vanished worlds with a fidelity that bones alone could never offer. In studying how ecosystems rose and fell across deep time, science finds not only a record of the past, but a lantern fo
