Tool-use in Chimpanzees

Chimpanzees use tools to capture food and social exhibits using it, have a sophisticated hunting strategy that requires collaboration, influence, and hierarchy, status recognition, calculation, and deception. They are skilled for future countries or events, including several interpersonal combinations, digital concepts and digital sequences. Chimpanzees often report on the use of tools.

You can write the whole article about the chimpanzee use tool, but only one (awful) example is enough. In 2007, researchers in Senegal in Africa used weapons to record more than 20 chimpanzees during hunting and pierced sharp branches into the holes of the tree to stimulate the baby in the jungle they contracted. Surprisingly, adolescent women are more likely to participate in this behavior than adolescent men and adults of all sexes, this hunting technique is not particularly successful, only jungle babies are fine It will be extracted. (Chimpanzees use the tools in a more peaceful way, open the tree with rocks and pull out water from the recesses in the leaves.)

Chimpanzee Stone Anvil, Palm Tree Hammer, Ali Strike Tool, and Senegal Spear Investigator observe that chimpanzees grab the ball on the stick and face it Bush's baby sleeping in a hole in the tree It was the first time to observe chimpanzees with hunting tools. (Special sample by Dr. Jill · Plutz, Iowa State University)

There are differences in the use of tools by invertebrates. Chimpanzees in Thai national parks may only use tools, but Gombe 's chimpanzees depend almost exclusively on tools to consume driving ants. This may be due to different rewards derived from using the tool. Gombe chimpanzees collect 760 ants per minute, but large chimpanzees collect 180 ants per minute. Some chimpanzees use tools to kill big bees (Xylocopa sp.) That make nests on the roads and in the withered branches in the trees. In order to get gr and honey, chimpanzees first use the stick to detect the entrance to the nest and test the presence of adults. If present, adult bees will prepare to stop their stomach entering and stab their stomach. Then chimpanzees use sticks to invalidate them, so that they will eat as soon as they fall. After that, chimpanzees spread teeth and branches and get gr and honey.

All chimpanzee people are recording the use of tools to obtain food. Rods, rocks, grasses and leaves are commonly used materials converted into utensils for obtaining and eating honey, termites, ants, nuts and water. These tools may seem too rough to think of as real instruments, but there is certainly evidence that you need to be foreseen and skillfully made to make and use them. For example, in order to extract honey from unthorn bee urticaria, chimpanzees use a short bar stripping the leaves, branches and bark to remove it most effectively from the nest. On the other hand, in order to extract honey from aggressive African honey hives, chimpanzees use rather long and thinner sticks to avoid stinging these bees (Stanford et al. 2000).
