A recent study published in the Journal of Mammalogy, at Oxford University Press, highlights that over 1000 new species of mammals have been described globally during the last dozen years, a finding that contradicts the notion that our mammalian relatives are well known. This rate of species discovery parallels that seen in global amphibians, and is driven by advances in DNA analysis methods and field exploration. This new listing of all living mammal species is now publicly accessible in the Mammal Diversity Database, a website funded by the American Society of Mammalogists and National Science Foundation that seeks to continue updating mammal species data to reflect newly published research.
