Observations of captive apes suggest they, like humans, have ‘social’ births
Like humans, African apes called bonobos may treat birth as a social event with a serious purpose.
In three recorded instances in captivity, female bonobos stood close by and provided protection and support to a bonobo giving birth to a healthy infant. Female bystanders also gestured as if ready to hold an infant before it was born, or actually held one as it was born, scientists report online May 9 in Evolution and Human Behavior.
