Paternal kin recognition in the high frequency / ultrasonic range in a solitary foraging mammal.

摘要: Kin selection is a driving force in the evolution of mammalian social complexity. Recognition paternal kin using vocalizations occurs taxa with cohesive, complex groups. This first investigation recognition via small-brained, solitary foraging mammal, grey mouse lemur (Microcebus murinus), frequent model for ancestral primates. We analyzed high frequency/ultrasonic male advertisement (courtship) call and alarm call. Multi-parametric analyses calls’ acoustic parameters discriminant function showed that calls, but not contain patrilineal signatures. Playback experiments controlling familiarity females paid more attention to calls from unrelated males than their fathers. Reactions fathers did differ. 1) Findings provide evidence solitarily mammal. 2) High predation, small body size, dispersed systems may select ranges, thus limiting risks inbreeding eavesdropping by predators or conspecific competitors. 3) Paternal mammals dependent upon large brain complexity, already have been an integral part networks which complex, kin-based sociality emerged.
