    Mouse Lemurs

    Morphological species concept- organisms can be classified is on the basis of morphology, or physical features. Issue with using this concept - example: mouse lemurs look very similar to each other but are actually at least 18 distinct species.

    This is a difficult group and variation in genitalia within species may indicate the presence of species complexes. Molecular data should be included in future revisions of this genus as an independent test of species concepts.
