DNA analysis reveals there are four distinct giraffe species, not one as previously thought
Researchers have long recognized only a single species of giraffe, thought to be made up of several subspecies. However, a research collaboration has now identified four distinct species. Conservation biologist Julian Fennessy of the Giraffe Conservation Foundation, geneticist Axel Janke of the Senkenberg Research Institute, and their colleagues collected and analyzed samples from giraffes across the African continent. Their results appear in the journal Current Biology.
