Scientists have developed the first map of the world's most unique and most endangered mammals and amphibians. The map highlights the fact that only a fraction of the areas identified as critical for the conservation of these species are protected. “If you look at mammals, if you look at just evolutionary history, the species that are more different from all others, the deep rooted ones tend to be in South America,“ Prof Jonathan Baillie, Director of Conservation at ZSL told BBC News. “That kind of simple action can ensure that those species can be there hopefully for hundred of years to come.“
