324-Million-Year-Old Amphibious Insect Fossil Reveals Evolutionary Link to Land Adaptation

A 324-million-year-old insect fossil, identified as an adult female named Chosha praecursor, has been discovered, offering a crucial evolutionary link between aquatic and terrestrial life forms. Published in Nature, the findings indicate that this ancient insect, found in shallow-water deltaic deposits, retained paddle-shaped abdominal appendages for swimming while also exhibiting features adapted for land, providing a snapshot of the transition to terrestrial life.
