  4. Jul 18, 2018 · Rice’s Justin Hayles and his colleagues, led by Peter Crockford at McGill University in Montreal, analyzed samples from an ancient Canadian lake bed that turned up anomalous oxygen isotopes embedded in deposits of sulfate. The oxygen provides hints at the extent of life on ancient Earth’s surface.
