Wild orangutans show communication complexity thought to be uniquely human

Researchers have found that wild orangutans vocalize with a layered complexity previously thought to be unique to human communication, suggesting a much older evolutionary origin.

OK this is great fun. #Chimpanzee drumming displays #rhythm -- the first time they seem to share roots of human #music
E. And W. Chimps have different drumming rhythms.

'We show that wild chimpanzees drum with non-random timing and isochrony, providing evidence that rhythmic drumming on instrumental substrates may have been present in our last common ancestor.2 Furthermore, we found subspecies-level regional rhythmic variation, showing that western chimpanzees drum isochronously, while eastern chimpanzees drum by alternating shorter and longer inter-hit intervals. Western chimpanzees also produce more drumming hits, drum at a faster tempo, and integrate drumming earlier in the pant-hoot vocalization, typically during the rhythmic build-up phase'

'Scientists who studied their chats in detail found that they took "fast-paced turns" when they exchanged information and also occasionally interrupted one another.

The revelation suggests "deep evolutionary similarities [with humans] in how face-to-face conversations are structured," said Prof Cat #Hobaiter

Chimps share humans' 'snappy' conversational style

Wild chimpanzees, like humans, take fast-paced turns in conversation, and often interrupt each other.
