How did humans survive in the Ice Age 25 thousand years ago?
You must have heard about the Ice Age, that at that time most of the earth was covered with ice. At that time, the ancestors of humans still lived on earth. However, the beginning of modern humans is believed to be from Homo Sapiens. Their history is said to be about three lakh years old. It was almost difficult for humans to live among huge icebergs. Wenli Li of the university of Chinese Academy of Sciences in beijing has revealed that humans once lived on the high Tibetan Plateau during the coldest period in the ancient 2.5 million years.
The Tibetan Plateau was never habitable
A new scientist has reported that the Last Glacial Maximum, which lasted from 26,500 to 19,000 years ago, was the most severe phase of the Pleistocene Ice Age. At this time, vast ice sheets and polar ice caps covered large parts of the Earth, while global temperatures were about 4 degrees Celsius to 5 degrees Celsius lower than today's average temperature. Wenli Li of the university of Chinese Academy of Sciences in beijing says that it was previously believed that the Tibetan Plateau was not habitable during the last glaciation. At that time, extreme cold, very little food and low oxygen levels at high altitude made life very difficult.
Evidence of humans found there
Although the evidence found there has shown that humans lived on the plateau before and after the Last Glacial Maximum, there have been no signs of any kind of occupation during this time. In 2019, Li and his team discovered a site 3,800 meters above sea level in the Yarlung Tsangpo River Valley on the southern Tibetan Plateau. Some artifacts were found in this site, which indicated human habitation there.
Researchers discover 427 artifacts
Researchers have so far discovered 427 artifacts in Tibet, including stone tools and a red-colored rock similar to ochre, used in ancient art. Radiocarbon dating of ancient bones and charcoal from the site revealed three distinct time periods of human habitation between 29,200 and 23,100 years ago. Two of these time periods coincide with the Last Glacial Maximum, about 25,000 and 23,000 years ago.
