Using long-term data from the Tsimane, we show that the differences between boys and girls in how their object play develops are linked to the different subsistence roles of men and women.

The APE Group has a typical bonobo/chimpanzee-like fission-fusion social structure 😄 This foraging sub-group (or ‘party’) is saying goodbye to our emigrating female Anaïs! We so enjoyed your stay with us!!

TLDR: new paper headed up by @vestaeleuteri.bsky.social
& with an awesome team, incl @andrearavignani.bsky.social , showing chimps have rhythm in their drumming & differences b/w east & west drum rhythms!

Chimpanzee drumming shows rhythmicity and subspecies variation
Chimpanzees drum on the buttress roots of trees for communication. Eleuteri et al.
investigate the presence of key elements of musical rhythm and of regional variation
in chimpanzee buttress drumming....
