And W. Chimps have different drumming rhythms.</p><p>'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'</p><p><a href="https://c.im/tags/primatecommunication" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>primatecommunication</span></a> <a href="https://c.im/tags/greatapes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>greatapes</span></a> <br><a href="https://www.cell.com/current-biology/fulltext/S0960-9822(25)00448-8" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">cell.com/current-biology/fullt</span><span class="invisible">ext/S0960-9822(25)00448-8</span></a></p>
