The Erligang culture was centered in the Yellow River valley. Erligang was the first archaeological culture in China to show widespread use of bronze vessel castings. In its early years, the culture suddenly expanded rapidly, reaching the Yangtze River, as evidenced by the largesite at Panlongcheng in Hubei.
The Yangtze carves through China's Three Gorges region, where previous sediment analysis dated the river to a mere one to two million years old. But these sediments must have been deposited long after the Three Gorges were initially cut, the study suggests.
