DNA reveals four gentoo penguin species instead of one after more than 100 years. Scientists now fear some island populations could lose their homes to global warming

New genomic research has resolved a century-old debate over gentoo penguins, revealing four distinct species rather than one with several subspecies. The newly recognised Kerguelen gentoo lives on remote islands in the Southern Indian Ocean. Scientists warn that warming temperatures could shrink habitats for several island populations, making conservation increasingly important.
