Genetic analysis uncovers four species of giraffe, not just one
Up until now, scientists had only recognized a single species of giraffe made up of several subspecies. But, according to the most inclusive genetic analysis of giraffe relationships to date, giraffes actually aren't one species, but four. The unexpected findings highlight the urgent need for further study of the four genetically isolated species and for greater conservation efforts for the world's tallest mammal, the researchers say.

Male giraffes are more socially connected than females. Although female giraffes have closer 'friends' than male giraffes, male giraffes have more 'acquaintances' than females, according to new research. The study demonstrates that giraffes form a complex multilevel society that is driven by differences in the social connections among individuals, which could have conservation implications for the endangered giraffes.
