What's the significance of the discovery of Homo sapiens?

Yiyuan County, Shandong Province, China has a long history, which is ancient and magical. As early as 400,000 ~ 500,000 years ago, Yiyuan Ape, the ancestor of Shandong people, thrived here.

Yiyuan ape-man fossils were found in the northeast of Jiuhui Village, Tumen Town, Yiyuan County, at the root of Dongshan Mountain and south of Xiaya Cave in Qizi Anshan. They are two ape-man skulls, two eyebrow bones, eight teeth, a humerus, a femur and a rib, and 10 bones of many accompanying animals.

After identification, these fossils are indeed the remains of Paleolithic apes, belonging to ancient human fossils unearthed by more than two apes, and are in the same era as the world-famous "Beijingers".

Yiyuan, located in the middle of Shandong Province, China, is the county with the highest average elevation in the province. Known as "the roof of Shandong", the birthplace of yi river. Its territory is connected with low mountains and rivers.

There is a "Nine Heaven Cave" in Yiyuan, so it is called "Nine Days" because there are nine layers of heaven in myths and legends, that is, nine days, and there are nine big holes in this cave. Together with the mythical Tiangong, the landscape can be beautiful, so it is called "Nine Heaven Cave".

Yiyuan has beautiful scenery and belongs to the warm temperate semi-humid continental monsoon climate, with good vegetation and humid climate. Tumen Town is surrounded by mountains and waters, with a beautiful environment. A place with mountains and water is often a spiritual place. The local geographical environment and climatic conditions are particularly suitable for human survival.

In terms of geology and geomorphology, Yiyuan does have its unique conditions. The limestone hills in central Shandong are gentle, the valleys are not deeply cut, and the ground is not undulating. In this range, there are at least hundreds of caves, which are rare in China and are known as the "hometown of caves in the north".

In ancient times, the climate of Yiyuan was much warmer and wetter than it is now. At that time, the average annual temperature in Yiyuan was higher than now, and vegetation tended to flourish and animals flourished in the tropical climate of North Asia, which was very suitable for ancient human life. All these advantages show that this place was once the cradle of ancient human survival and reproduction.

The ancient Yi River has a long history and ancient myths are widely circulated. Perhaps the legendary Yihua girl is the ancient Yiyuan people.
