Scientists working in Madagascar announced Monday they have discovered three previously unknown species of mouse lemurs, the world's smallest primate.
Lemurs are the most primitive primates and are among the world's most endangered species.

Madagascar is the world's only home to about 40 species of lemurs, including two previously known species of mouse lemurs. An international team confirmed the new varieties by genetic tests, as well as by small differences in their skulls, teeth and other physical characteristics. Other participants were from Germany and Madagascar.
