Wisconsin Man Sentenced to 49 Years for Repeated Child Sexual Assault and Pornography

Researchers at Johns Hopkins University have discovered that bonobos possess the ability to recognize ignorance in others and communicate accordingly, a cognitive skill previously thought to be unique to humans. The study, published in PNAS, involved three bonobos at the Ape Initiative research center in the United States.
In the experiment, bonobos were tested in cooperative settings involving a hidden grape reward. When the human partner, Luke Townrow, asked where the grape was, the bonobos pointed to the correct cup especially when he had not witnessed its placement. "This indicates that they understand their partner's lack of knowledge," stated lead author Christopher Krupenye, a psychology professor at Johns Hopkins.
The findings align with earlier studies suggesting that bonobos, closely related to humans, have sophisticated social abilities. As noted by primatologist Josep Call from the University of St Andrews, “there are other results in the literature that are consistent with what they found.” The research highlights the evolutionary roots of complex cognitive behaviors shared among primates.
