Data analysis navigates lookalikes to try to pin down the true number of mouse lemur species

In some parts of the world, animals are going extinct before scientists can even name them. Such may be the case for mouse lemurs, the saucer-eyed, teacup-sized primates native to the African island of Madagascar. There, deforestation has prompted the International Union for the Conservation of Nature (IUCN) to classify some of these tree-dwelling cousins as "endangered" even before they are formally described.
