Abstract
- Defined as the killing of a newborn individual by a conspecific, infanticide by males is widespread in mammals. Results from this paper used genetic analysis to confirm and characterize the first report of non-parental infanticide in giant armadillos. Genetic evidence demonstrates that the killer male is unrelated to the killed infant but is the father of the next offspring. This evidence supports the sexual selection hypothesis, in which infanticide is used to obtain increased access to breeding females. [ABSTRACT FROM AUTHOR]
