By Associated Press Scientists working in Madagascar say 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.
The newly discovered lemurs represent a small but encouraging sign to conservationists. 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. The three newly discovered species inhabit only the dry, dense forests along the island's west coast.
