Do chimpanzees eat their own babies?
The creatures are known to sometimes kill newborn babies that they have not fathered, occasionally even eating the young after snatching them from their mother’s arms. The reason for this behaviour is unclear, but scientists believe it presents the males with greater breeding opportunities.
Male animals of many other species are known to kill young infants that aren’t related to them. This allows them to mate with the mother, and to have more of their own offspring in the group. … The baby chimp may simply have been a source of nutrition to the adult that snatched it, says Nishie.
