Chimps tools

Chimps are much better at termite fishing than we are. Tool modification is extremely rare in the animal world which is yet another example of how chimps and humans are so similar. In another group of chimps, different from the culture that Jane Goodall studied, there was a discovery of a hammer and anvil tool top of page being used to crack open hard nut shells.

An anvil is a hard surface that is used to place something on while it is hit with a hammer to crack it. This is a perfect example of yet another similarity between chimps and us humans. What do you use to crack open nuts? We have all sorts of tools for nut cracking and they come in a variety of shapes and sizes. Chimps use different sized rocks as hammers to crush a hard nut on top of a larger rock, which is the anvil. Chimpanzees also use different tools in different areas to drink water from holes in trees.

This water is often too deep for them to reach with their mouths so they must find other ways to access it. In some places chimps chew up leaves and spit them out to make an absorbent sponge which they then use to suck up the water.

When they take it out of the tree it is full of water that can be easily sucked off of the sponge. Other chimps use tools like a straw to drink water from these holes. Chimpanzees are very creative when it comes to making tools for all sorts of jobs. Chimpanzees also hunt for their food just like humans do.

Chimps have been seen creating and using primitive spear-like tools to catch small nocturnal primates, which sleep in the holes of trees. Because these holes tend to be quite deep, chimps cannot simply reach their hands down into them to get their prey. These chimps have learned how to create sharp spears with their teeth, which they can then poke into these holes.

The sticks are much longer than their arms and therefore they can reach their prey. Message from CAC'ers. When we were in Tanzania we saw many termite mounds that chimps termite fish at. Some of them even had left over tools that the chimps had used next to them! Termites build complex nest structures that encompass a network of below-ground chambers, sometimes topped with a towering, freestanding mound reaching several meters high.

Chimpanzees in both locations use fishing-probe style tools to harvest termites, but Goualougo chimpanzees use multiple, different types of tools sequentially. They also make tools from specific plant species and customize fishing probes to improve their efficiency. The researchers found differences in the rate, probability, and types of tool transfer during termite gathering between these two populations.

At Goualougo, where the fishing tasks were more complex, the rate of tool transfer was three times higher than at Gombe, and Goualougo mothers were more likely to transfer a tool in response to a request. Further, mothers at Goualougo most often responded to tool requests by actively giving a tool to offspring. Such active transfers were never observed at Gombe, where mothers most often responded by refusing to transfer tools. Given that offspring in both populations made comparable requests for tools, these differences suggest that mothers at Goualougo were in fact more willing to provide tools.

Understanding how chimpanzees pass on tool traditions over generations can provide insights into the evolutionary origins of complex cultural abilities in humans.

Conservation efforts are fundamental to this research and future studies. Studying our closest living relatives offers a unique opportunity to gain insights into the evolutionary origins of cultural behavior—but this privilege depends on long-term efforts to conserve these apes and their habitats.
