Long ago, people lived in China.
They lived near big trees and grass. They lived with deer and big elephants.
These people used stones to make tools. They made tools to scrape and cut. They found teeth and a leg bone. The teeth belonged to a young boy. The bone belonged to a young girl. These old things help us learn about them.
Long ago, early humans lived in China. One group is called Yuanmou Man. They lived in the Yuanmou Basin. This area had grass, bushes, and forests.
These people lived about 1.7 million years ago. They shared the land with many animals. They lived near deer, pigs, and rhinos. They even lived near big elephants called Stegodon.
Scientists found clues about these people in the ground. They found two large teeth from a young male. They also found a leg bone from a young female.
The female may have stood about 1.1 meters tall.
These early humans were very smart. They made tools out of stone. They used rocks called quartz to make them. They used a hammerstone to hit the rocks. This made sharp flakes and scrapers. They used these tools to work. These tools are like the ones used by other early humans in Africa. Finding these items helps us learn how they lived so long ago.
Yuanmou Man was a type of early human. They lived in the Yuanmou Basin in China. This place is in the Yunnan Province. These people lived a very long time ago. Most scientists think they lived about 1.7 million years ago. They are some of the oldest human fossils found in China. Finding them helps us see how early humans moved across Asia.
These early humans lived in a changing world. Their home had many different parts. There were open grasslands and thick bushlands. They also lived near marshlands and forests. These forests had many pine and alder trees. They shared this land with many animals. They lived near deer, pigs, and rhinoceros. They even lived near a huge elephant called Stegodon.
We know about them because of fossils found in the ground. In 1965, a geologist named Qian Fang found two large teeth. These teeth belonged to a young male. Later, in 1984, a team found a leg bone. This bone is called a tibia. It belonged to a young female. She may have stood about 1.1 meters tall.
Scientists have worked hard to find the right age for these fossils. It is a hard job because the rocks have moved. In 1976, researchers used the Earth's magnetic field to find a date. Other scientists used different methods to check the age. Some thought the fossils were only 0.6 million years old. However, many experts now believe the 1.7 million year date is correct. This helps us place them in the Lower Pleistocene time.
Even though they lived long ago, they were very skilled. Yuanmou Man made many stone tools. They used rocks like quartz and quartzite from nearby rivers. They used a hammerstone to hit the rocks. This made sharp flakes, choppers, and scrapers. They used a way called direct hammering to shape them. They also used a bipolar technique by smashing the rock. These tools are very similar to tools used by humans in Africa.
Yuanmou Man, scientifically known as Homo erectus yuanmouensis, is a subspecies of early human. These ancestors lived in the Yuanmou Basin within the Yunnan Province of southwestern China. They are considered some of the earliest human specimens discovered in China. Studying these fossils helps scientists understand how early humans spread across the Asian continent. This discovery provides a vital link in the history of human evolution in East Asia.
The fossils we know about come from two very different types of remains. The first discovery consisted of two upper first incisors, which are the front teeth used for biting. These teeth belonged to a young male. The second discovery was a partial tibia, which is the large bone in the lower leg. This bone belonged to a young female. Based on this tibia, scientists believe the female may have stood about 1.1 meters tall in life.
These early humans lived in a diverse and changing environment. The Yuanmou Basin offered a mix of open grasslands and thick bushlands. There were also marshlands and forests filled with pine and alder trees. They shared this landscape with many large animals. They lived alongside deer, pigs, rhinoceros, and cattle. They also encountered the Stegodon, which was a type of elephant, and the giant short-faced hyaena.
Determining exactly when Yuanmou Man lived has been a complex scientific challenge. The rock layers in the basin are faulted, meaning the Earth's movement has displaced the rock masses. This makes dating the area through animal remains, a process called biostratigraphy, very difficult. In 1976, researchers used palaeomagnetism to date the teeth. This method looks at the history of the Earth's magnetic polarity. They linked the teeth to the Gilsa geomagnetic polarity event. This placed the date at roughly 1.7 million years ago. Other scientists used different methods, such as measuring protein ratios in bones, which gave much younger dates. However, most experts now agree that the 1.7 million-year date is the most accurate.
The discovery of these fossils happened in stages through careful fieldwork. On May 1, 1965, a geologist named Qian Fang found the two incisors. He found them in fossiliferous deposits near Shangnabang village. His team was funded by the Chinese Academy of Geosciences. Later, in December 1984, a team from the Beijing Natural History Museum found the tibia. They found it at the Guojiabao site, which is near the original discovery location. This tibia was eventually described in 1991.
Yuanmou Man possessed impressive technology for their time. They manufactured various stone tools using materials like quartz and quartzite. These rocks were likely gathered from nearby rivers. They created simple cores, flakes, choppers, pointed tools, and scrapers. To make these, they used a method called direct hammering. This involves using a hammerstone to flake off pieces of the rock. They also used a bipolar technique, which involves smashing a core with a hammerstone. These tools are very similar to the Oldowan technology used by humans in Africa at the same time.
The study of Yuanmou Man connects to the larger story of human migration. They were part of a major expansion of Homo erectus across Asia. This species lived in many places, from northern China down to Java. Some scientists believe that different groups of humans moved into East Asia at different times. For example, dental comparisons suggest that the people in Java may have arrived through a different dispersal event than the Peking Man. Yuanmou Man helps researchers test these theories about how our ancestors moved across the world.
