"Unveiling the Mysteries of Evolutionary Stagnation in Ancient Fish Hybrids"

TL;DR
The discovery of a hybrid fish, the Alligator Gar x Longnose Gar, has revealed the oldest parental split of any animal, plant, or fungi hybrid, dating back 100 million years. This finding sheds light on the slow evolution of gars, often considered "living fossils", and their ability to create viable hybrids with other species despite not sharing a common ancestor for millions of years. The study of gars could provide insights into DNA repair and potential implications for human health and cancer research.
