We used brain imaging techniques to show these two activities engage the same region of the brain. Then we wanted to find out more.

Capuchin monkeys in Brazil use big stones to crush the shells of nuts they want to eat. An experiment in the field investigated how these monkeys prepare to use new, unfamiliar tools.

Species that use tools aren’t necessarily better at solving problems than species that don’t.
The stone flakes are flying, but what brain regions are firing?

We can’t observe the brain activity of extinct human species. But we can observe modern brains doing the things that our distant ancestors did, looking for clues about how ancient brains worked.
Chimpanzees performed a specific technique with a stick to extract underground bees nests.
New, fascinating observations about the behaviour of wild chimpanzees showed that they can apply a complex technique to access honey.
The Spangled Drongo is a frequent mimic.
Australian birds are arguably among the smartest in the world, displaying complex behaviours comparable to those observed in great apes.
A right sponger.
The use of tools is one example of the growing capacity for analytical thought and invention in apes and early humans. The earliest flint-knapped stone cutting tools date from around 2.6 million years…
