We present the first cladistic analysis sampling multiple representatives of most major groups based on DNA sequence for three nuclear (GHR, RAG1, AP5) and one mitochondrial (COII and parts of COI and ATPase 8) fragments. Analyzed separately, the four partitions agree broadly with each other and the combined analysis. The basal split is between a clade of Philippine Old Endemics and all remaining murines. Within the latter, rapid radiation led to at least seven geographically distinct lineages, including a Southeast Asian Rattus clade; a diverse Australo-Papuan and Philippine clade; an African arvicanthine group including the otomyines; an African Praomys group; and three independent genera from Africa and Asia, Mus, Apodemus, and Malacomys. The murines appear to have originated in Southeast Asia and then rapidly expanded across all of the Old World. Both nuclear exons provide robust support at all levels. In contrast, the bootstrap proportions from mitochondrial data decline rapidly with increasing depth in the tree, together suggesting that nuclear genes may be more useful even for relatively recent divergences (<10 MY).} }
