Female-led infanticide in wild chimpanzees

Current Biology, Volume 17, Issue 10, 15 May 2007, Pages R355-R356

You may not be able to see the article, so here is the main finding:

Infanticide by male chimps has been documented at all places where these animals are observed. Jane Goodall had once observed female infanticide but interpreted the incident as the attack by a pathological female. Now there is new evidence of coalitionary infanticide by females attacking females not belonging to the group (or new arrivals), taking away their newborns and killing these with a bite in the head.
