Young chimps play weird with tools and other objects & this can lead to innovation! Moss sponging, doll play, leaf clipping to ask for carrying. If copied and retained, rare kid innovations can contribute to cultural complexity 🧪🔬🐵

To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

The first empirical chapter of my PhD and the fruit of a hugely collaborative project led with Franziska Wegdell and Johanna Schick is out! We explore if immature-directed vocalisations are present and in what quantity in wild great apes.

The evolution of infant-directed communication: Comparing vocal input across all great apes
Human infants receive more directed communication than other great ape infants, indicating that it evolved alongside language.

"Emotion leaves a trace in their voice - just like humans." Venkatraman Manikandan shared a clever, practical approach for AI monitoring of chicken vocalizations that could work across entire flocks to get a full picture of #animalwelfare #UFAW2025. Read about it 👇
