Scientists split gentoo penguins into four species, one totally new to science

Phys · · 1491 words · By Robert Sanders

An international team of biologists has identified that gentoo penguins consist of four distinct species rather than one, including one previously unknown species. The research, published in Communications Biology, utilizes genomic analysis to explain how these species adapted to different environments and warns that climate change may threaten the survival of the island-dwelling species.
