Has vicariance or dispersal been the predominant biogeographic force in Madagascar? Only time will tell

Article Abstract:

Madagascar is one of the world's hottest biodiversity spot due to its diverse, endemic and highly threatened biota which shows a distinct signature of evolution in isolation, both in high levels of diversity within lineages and in the imbalance of lineages. A comprehensive sample of phylogenetic studies of Malagasy biota are reviewed which indicate that the predominant pattern is one of sister group relationships to African taxa.
