A new hominid from the Upper Miocene of Chad, Central Africa
The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.

Phylogeny and biogeography of African Murinae based on mitochondrial and nuclear gene sequences, with a new tribal classification of the subfamily
The authors' molecular survey of Murinae indicates that there were at least four separate radiations within the African region, as well as several phases of dispersal between Asia and Africa during the last 12 My. Expand
Multiple Geographic Origins of Commensalism and Complex Dispersal History of Black Rats
Three of the four phylogenetic lineage units within R. rattus show clear genetic signatures of major population expansion in prehistoric times, and the distribution of particular haplogroups mirrors archaeologically and historically documented patterns of human dispersal and trade. Expand
Hantavirus in African Wood Mouse, Guinea
Sequence and phylogenetic analyses of the genetic material demonstrate a novel hantavirus species, which the authors propose to name "Sangassou virus". Expand
Taphonomy and palaeoecology of Olduvai Bed-I (Pleistocence, Tanzania).
The interpretation of the palaeoenvironments is that the middle Bed-I faunas indicate a very rich closed woodland environment, richer than any part of the present-day savanna biome in Africa, changing to less rich woodland in upperBed-I with a trend towards more open and seasonal woodlands at the top of the series.

Cytochrome b-based phylogeny of the Praomys group (Rodentia, Murinae): a new African radiation?
Complete cytochrome b gene sequences allows, for the first time, establishing a nearly complete phylogeny among the Praomys group sensu lato and the different lineages probably result from an adaptive radiation at the end of the Miocene. Expand
New Phiomorpha and Anomaluridae from the Late Eocene of North-West Africa: Phylogenetic Implications
Until recently, the ancient fossil family Phiomyidae (suborder Hystricognathi) was recorded only from the early Oligocene site of the Fayum, Egypt (Andrews, 1906; Osborn, 1908; Schlosser, 1910, 1911;Expand
Assessment of Three Mitochondrial Genes (16S, Cytb, CO1) for Identifying Species in the Praomyini Tribe (Rodentia: Muridae)
Using DNA markers for identifying species in the Praomyini tribe is a largely valid approach, and the CO1 and Cytb genes are better DNA markers than the 16S gene, which confirms the usefulness of statistical methods such as the Random Forest and the 1-NN methods to assign a sequence to a species, even when the number of species is relatively large.

The phylogeny of the Praomys complex (Rodentia: Muridae) and its phylogeographic implications
A cladistic analysis of the relationships within the Praomys complex and of the genera Hylomyscus, Mastomys and Myomys shows that the different clades each present a relative ecological cohesion and are arranged according to a gradient from closed to open habitats. Expand
