Savanna chimps in Senegal use the same ant-dipping strategies as forest populations — because ant aggressiveness, not habitat type, is what drives tool use. New research from Dindefelo unpacks why. #Primatology #Chimpanzees https://www.primatology.net/p/what-the-ants-tell-us-about-chimpanzee
What the Ants Tell Us About Chimpanzee Culture

The strategies savanna chimpanzees use to harvest army ants look almost identical to what forest populations do — and that’s the surprising part

‘To them a power line is a line of trees’: Costa Rica moves to protect howler monkeys from electrocution

Electric shock is one of the biggest causes of death among wildlife in the country but a court ruling is a first step to making power lines safe

New research: chimpanzee quartets outperform pairs at sustaining a shared resource — and it’s the dominant animal eating less that makes the difference. A fascinating wrinkle in great ape cooperation. #Primatology #HumanEvolution #ChimpanzeeResearch https://www.primatology.net/p/when-the-boss-eats-last-chimpanzee
When the Boss Eats Last: Chimpanzee Groups, the Tragedy of the Commons, and a Leadership Paradox

New research shows that chimpanzee quartets outperform pairs at sustaining a shared resource — and the reason why upends assumptions about dominance and cooperation.

💁🏻‍♀️ TIL: Researchers traveled to remote #Boé National Park in #GuineaBissau to study accumulative stone throwing, a rare behavior where male western #chimpanzees repeatedly hurl #rocks at specific #trees while calling out and drumming. 🌳

The team used camera traps to gather #data on what these chimpanzees might be communicating, and whether the behavior is a form of #animal #culture. Some sites have been used for over a decade. 🐒

Why do male chimpanzees throw rocks at the same trees for more than a decade? We travelled to remote Guinea-Bissau to find out

To study accumulative stone throwing among wild chimpanzees, researchers hike deep into the savanna-woodland of Boé — a habitat increasingly threatened by industrial mining.

🧠🔢 Psychologists from #Bucknell and #Drake Universities discovered that while #reading habits influence how we map numbers, our mental number lines are highly individual.

By studying #primates and #birds, researchers found that #animals also organize quantities spatially, suggesting this mental mapping is biological.

How you map numbers in your mind isn’t universal, even among people who read the same language

On your mental number line, are the numbers smaller on the left or on the right? Two comparative cognition researchers explain how culture may influence the orientation – but also may not.

New evolutionary data reveals human carpal bones didn't diverge from knuckle-walking ancestors—they were built directly on top of those traits.
