Paternal care is generally, although not exclusively, associated with monogamy in mammals. The Algerian mouse, Mus spretus, is a nocturnal murid living in xeric habitats in northern Africa, the Iberian peninsula and the south of France. We compared the amount of paternal care induced by removing young in Mus spretus and in the polygamous house mouse M. musculus domesticus in terms of the evolution of paternal care during the first 10-days post-partum and absolute (father alone) and relative (both parents) values. We then recovered indirect evidence of young being cared for by males from field data. The results were unambiguous in showing that the two species differed dramatically in paternal behaviour, with no variation being observed during the initial pup development. Mus spretus dedicated half of its time to caring from the young against less than 10% in M. m. domesticus. The former species showed the same number of retrieving acts and direct care bouts both in the presence and in the absence of the mother. Merging these results with field observations of spatial association male-young until subadult age, we drew conclusions on the likely occurrence of paternal care in M. spretus. Taken together with our previous results on socio-spatial organisation and pair bonding, we propose that social monogamy is advanced for this species.
