Story summary

A genomic study identifies three distinct subspecies of the endangered yellow-eyed penguin, hoiho, each adapted to different oceanic territories.
Researchers from the University of Otago, the Department of Conservation, and Ngai Tahu used whole-genome sequencing from nearly 250 penguins across New Zealand and the subantarctic islands.
The subspecies diverged between 5,000 and 16,000 years ago.
Professor Jemma Geoghegan warns that without immediate conservation efforts, one subspecies could face extinction.
