A new study concludes that when it comes to controlling emotions, baby chimps do it better than human babies.
The research, which investigated the facial expressions of young chimpanzees, may explain why some babies cry so much and are so inconsolable.
In the study, scientists found that baby chimps almost always cry for a reason, in contrast to some of the crying of human babies.
"If you pick up a baby chimp when it's fussing [crying], it calms down and stays calm.
"Anybody who has had a fussy child knows it is well within the range of the human norm that if you pick them up then they are still fussy," said Professor Kim Bard of Portsmouth University.
