How Chimpanzees Teach Tools
Today on Uncovered, we'll explore how chimpanzees teach their young to use tools. In the wild, survival depends on passing down clever techniques, from fishing for insects with twigs to cracking open tough forest fruits.
Forest Classrooms
For decades, scientists wondered whether wild animals teach one another or whether young chimps work out difficult skills alone. In Senegal's Dindefelo Community Nature Reserve, researchers placed cameras at fourteen sites where chimps were already known to use tools. They reviewed nearly fifteen hours of footage captured from 2017 to 2025. The videos showed adults passing tools and food to younger chimps, giving researchers a rare chance to study learning in the wild. The study suggests that these handoffs can help young chimps practice skills they need to find food.
Active Animal Teaching
To call a behavior teaching, scientists use a careful test. The adult must act in a way that helps a learner pick up a skill, and the adult must pay some cost. Researchers recorded thirty-three stick transfers: nineteen during ant fishing, ten while chimps searched for algae, and four while they fished for termites. Those counts show that handoffs occurred across different foraging tasks. Together, the observations show more than one unusual moment. A young chimp can watch how a stick reaches into a nest, then get a chance to handle the tool itself.
Passing Down Tools
Think of it like learning to ride a bicycle. If someone steadies the handlebars and lets you try, you can learn faster than by guessing alone. Young chimps also need practice with difficult foraging skills: they use sticks to reach for insects, and they learn how to open baobab fruit against rocks. Researchers look closely at what the adult does, not just whether a youngster eventually succeeds. Helping must improve the pupil's chance to learn, and the adult must accept a cost. Passing over a useful tool can mean giving up a chance to keep foraging.
Hands-On Instruction
One camera recorded a mother named Soukki pushing a stick into an ant nest, then bringing her daughter Saïsaï to the spot. Saïsaï pulled out the stick and ate ants attached to it. The mother's action did not do the whole task for her; it placed a useful tool where the youngster could try it. Other recorded transfers showed adults handing tools directly to juveniles. These moments let researchers see a young chimp move from watching an adult to handling a tool. The youngster still has to learn the movement, but the adult's help makes a first attempt possible.
Mastering Forest Skills
Researchers also looked at how chimps open baobab fruit. At eleven known sites, they analyzed thirty minutes of footage and recorded four food transfers. In one scene, a mother named Féré placed fruit near her infant, Fotti. Fotti tried to pound one against a rock but could not crack it. A young male, possibly an older brother, began hitting it against the stone while Fotti watched closely. After the fruit opened, Fotti ate a piece. The footage cannot tell us every thought inside the young chimp's mind, but it shows a youngster observing a demonstration and receiving food afterward. This gives researchers another example of a learning opportunity alongside the stick handoffs.
Protecting Wild Culture
Most of the recorded handoffs were between relatives. Adults accounted for fifty-eight percent of the chimps giving up tools, and infants were the largest recipient group at forty-two percent. Researchers also noticed that many adults used a tool less, or stopped using it, after passing it along. The young recipient used the tool more and fed more often. This pattern matters because it fits a scientific definition of teaching: the learner benefits while the teacher takes on a cost. It offers evidence about how skills can pass between generations without assuming chimps learn exactly as humans do.
Observing Animal Learning
There is still much to learn. The team wants to compare chimpanzees in other places to find out whether these teaching and helping behaviors are common or particular to the Dindefelo community. Researchers also ask whether young chimps that receive more guidance later become better teachers. A short video can show a handoff, but many observations help scientists understand how often it happens and what it means. You can try the same habit when watching animals near you: notice what one animal does, what another learns, and what evidence supports your idea.

Closing
Chimpanzee teaching is an active partnership where experienced adults share tools and pause their own meals so the next generation can thrive. Next time you see a mentor patiently guide someone through a new skill, remember that sharing knowledge is an ancient tradition across our family tree.
