Complementary approaches of cytogenetics and molecular biology to the taxonomy and study of speciation processes in lemurs

Abstract The lemurs, prosimian primates of Madagascar, constitute a zoological group containing numerous species and subspecies. Their taxonomy remains controversial. Depending on the authors and the techniques they have used, the number of species varies between 39 and 52. In addition, although a monophyletic origin of the settlement of Madagascar is the most commonly held opinion, recent studies based on molecular biology do not exclude two independent colonization events, one involving Daubentonia and a second giving rise to the other lemurs. 1 .
