A 70-million-year-old genetic rescue allowed codfishes to escape extinction and shape the North Atlantic

A new study has revealed how the repurposing of an ancestral gene saved the embryos of cod's ancestors from extinction, enabling them to form the large populations that, millions of years later, would change the course of human history. The codfishes and their relatives in the or
