Panamanian monkeys can now use tools, can they really evolve again?

If we think about it carefully, we will find that many animals actually use tools. For example, the crows we learned when we were young do use tools to drink water. They do do things by eating stones. They also know how to put nuts on the road. Cars crush it and then peck at the food crumbs on the road. Chickens will also peck at some small stones to help grind the food seeds they eat. Even small hermit crabs will find snail shells as small seeds. To protect themselves, sea otters use stones to open hard-shelled shellfish, crabs and other animals. Some birds also use stones to crack open the eggs of other birds to eat. As for monkeys, orangutans, baboons and other primates, there are even more such examples.

For example, macaques will use stones to break open shellfish, and you will use harder stone ground to break open nuts. Capuchin monkeys also often use stones to open nuts or use flake stones to dig out plant tubers. , Chimpanzees will use small branches to catch termites in termite holes. Some people have photographed orangutans using branches to test the depth of the river water in order to find the shallowest channel to cross the river. Orangutans in Indonesia use a variety of tools to steal They eat honey and hunt insects, and blow leaves with their mouths to scare away predators, or shake branches to drive away pythons. Some orangutans will use a huge leaf on their head as an umbrella to shelter from the rain when it rains...

It can be seen that using tools is not just a patent for humans, but a common phenomenon in the animal kingdom. However, making tools is very rare among animals. Only a few primates can use simple processing of branches, stones, etc. Make it a more convenient tool, but we humans are already very good at making tools. We even make tools that surprise us. For example, installing hundreds of millions of transistors on a chip the size of a fingernail, humans are manufacturing and using it. The ability to use tools is much stronger than that of any other animal, which shows that the intelligence and ability of animals are still far from that of humans.

Answering this question requires many considerations, because it is also very important to learn to walk upright, but being able to use tools with your hands will also promote upright walking. If these species are given enough time to evolve, and Having good evolutionary environments and conditions does not rule out that they will not evolve.
