A female chimpanzee engages in sex only during her fertile period, which is advertised by a swelling of her external genitals. Bonobos, the closest relatives of the chimpanzees, are more sexually active than chimpanzees. Female bonobos mate even when they are not fertile. In both species, mating is promiscuous; each female mates with many males. By one hypothesis, female promiscuity may help prevent male infanticide. Chimpanzee male have been observed to kill infants in the wild, but this behavior has never been observed among bonobos. Explain why it would be disadvantageous for a male to kill the infant of a female with whom he had sex. How the bonobos female might's increased sexual activity lower likelihood of male infanticide still further?
