In a surprising recent discovery revealed to the scientific community, East African chimpanzees have demonstrated remarkable intelligence and skills. According to new research findings, these adorable chimpanzees have entered the Stone Age.
The Incredible Evolution of Chimpanzees in East Africa: From Wild Primates to Stone Age Civilization
East African Chimpanzees (Pan troglodytes) are among the smartest primates in the world. They inhabit the forests of the eastern part of the African continent and have an astonishing evolutionary history.
Besides humans, it has been observed that East African chimpanzees have the ability to use tools. Initial studies indicate that they can use sticks as spears to catch small mammals for food. This is the first known example of chimpanzees using tools, showcasing their spontaneous problem-solving abilities.
Recent studies have shown that chimpanzees can even master skills such as digging and house-building, demonstrating not only intelligence but also revealing their complex social structures.
Further research indicates that these chimpanzees have learned to use leaves as drinking tools and rocks on the ground as bedding materials for sleeping. This shows that East African chimpanzees are highly skilled at utilizing a variety of tool applications, and this creativity and adaptability enable them to thrive in different environments.
The most notable evolutionary achievement of East African chimpanzees is their Stone Age civilization. Through long-term studies, scientists have observed behaviors within natural chimpanzee communities closely associated with native stone materials. They strike stones against tree trunks and branches to produce sounds with various meanings.
The remarkable evolutionary history of chimpanzees in East Africa provides a diverse picture of their relationship with tools, the development of stone technology, and the beginnings of civilization.
Even more astonishing is that when male chimpanzees build nests, they choose specific shapes and arrangements of stones to enhance structural stability. Their skills and creativity in using stones enable chimpanzees to construct more complex nests that can withstand wind, rain, and humidity, thus laying the groundwork for their civilization development.
In addition to using stones, East African chimpanzees also exhibit other stone crafting skills. Scientists have observed chimpanzees selecting hard stones, shaping them into specific forms, and then using them to catch insects or perform weapon-like attacks. The development of this stone tool technology indicates that East African chimpanzee society possesses a certain cultural inheritance, where technology has been accumulated and passed down.
Despite the vast distance between them and humans, the evolutionary history of East African chimpanzees still fascinates us and highlights the wonders and diversity of the natural world.
The evolutionary history of chimpanzees in East Africa provides us with invaluable evidence. Through observation and research, we learn about their close relationship with tools and the development of stone tool technology. This reflects their problem-solving abilities and adaptability to their environment, and even demonstrates certain cultural inheritance and creativity. This is an astonishing achievement for a non-human primate that shares similar evolutionary traits with humans.
It is also important to clarify that compared to human civilization, the development of civilization in East African chimpanzees is still relatively limited. However, this does not diminish the intelligence and creativity of East African chimpanzees.
The evolutionary journeys they demonstrate remain significant evidence of biodiversity and animal intelligence, serving as a reminder of our common ancestral relationship with them.
Revealing Intelligence and Complex Social Structure
Researchers have discovered that chimpanzees can learn skills such as digging and building, a finding that further illuminates their intelligence. In an experiment, researchers provided chimpanzees with simple tools such as sticks and stones and taught them how to use these tools to dig and build simple burrows. Remarkably, these chimpanzees quickly mastered these techniques and successfully dug wells and constructed simple homes.
These experiments demonstrate that chimpanzees not only have high IQs but also possess tool usage abilities and certain building skills. Chimpanzees can not only learn how to use tools but also improve and innovate these techniques by observing and mimicking their peers. This proves that chimpanzees have a high level of cognitive awareness and social intelligence.

The social structure of chimpanzees is also revealed through these experiments. Research shows that in the process of learning to dig and build, chimpanzees exhibit clear division of labor and cooperation. Some chimpanzees dig, some move materials, and others construct. This division of labor reflects the hierarchical structure and organizational pattern of chimpanzee society.
The cooperation among chimpanzees is not merely a series of individual actions but is based on complex social relationships and structures. Chimpanzee society has a clear concept of group hierarchy and territory, maintaining social group stability by establishing stable social relationships. The cooperative behaviors displayed by chimpanzees in experiments are rooted in this structure and social relationship.

Studies on chimpanzees’ proficiency in digging and building techniques reveal their intelligence and complex social structure. Chimpanzees not only have high IQs but also possess tool usage abilities and specific building skills. Research on chimpanzees not only helps us better understand these close relatives but also contributes to enhancing our understanding of human intelligence and social structure.
