Humans can understand apes’ sign language, new study finds

From pointing to animated arm movements and nodding, people regularly employ gestures to accompany and create language.

Now, it’s been suggested that humans can also understand sign language used by apes, meaning humans may retain an understanding of ape communication from their ancestors.

Great apes deploy more than 80 signals to communicate everyday goals, according to a study published Tuesday in the journal PLOS Biology.

Chimpanzees and bonobos, which share more than 90% of their gestures, are humans’ closest living relatives, the study said. Their gestures have been suggested to be an important framework in the evolution of human language, according to study authors Kirsty E. Graham, a research fellow at the University of St. Andrews’ School of Psychology and Neuroscience in Scotland, and primatologist Catherine Hobaiter, a principal investigator at the university’s Wild Minds Lab.

Infants ages 1 to 2 have been found to use more than 50 gestures from the ape repertoire, researchers said. It was therefore thought that humans may have retained their understanding of core features of ape gestures.

Pope warns Vatican staff an ‘elegant demon’ lurks among them

Pope Francis warned Vatican bureaucrats on Thursday to beware the devil that lurks among them, saying it is an “elegant demon” that works in people who have a rigid, holier-than-thou way of living the Catholic faith.

Francis used his annual Christmas greeting to the Roman Curia to again put the cardinals, bishops and priests who work in the Holy See on notice that they are by no means beyond reproach and are, in fact, particularly vulnerable to evil.

Francis told them that by living in the heart of the Catholic Church, “we could easily fall into the temptation of thinking we are safe, better than others, no longer in need of conversion.”

. . .

Beyond that, Francis appeared to also want to take broader aim at arch-conservatives and traditionalists who have become the pope’s biggest critics. Francis blasted their way of living the faith, insisting that being Catholic doesn’t mean following a never-changing set of dicta but is rather a “process of understanding Christ’s message that never ends, but constantly challenges us.”
