Bat Systematics in the Light of Unconstrained Analyses of a Comprehensive Molecular Supermatrix

Bats (Chiroptera) represent the largest diversification of extant mammals after rodents. Here we report the results of a large-scale phylogeny of bats based on unconstrained searches for a data matrix of 804 non-chimeric, taxonomically updated bat terminals (796 species represented by a single termi...
