The footprints of prehistoric people on Saudi Arabia's lush meadows offer new clues as to how we leave Africa.
At first it was just a fingerbone. Now, archaeologists working in Saudi Arabia find other traces of Africa that point to an earlier migration.
Human footprints were found near the city of Tabuk in the northwestern region of Saudi Arabia. According to the press statement issued by the Ministry of Culture and Information of the Kingdom, footprints were found scattered in different directions in an old lake bed once
Bulgular was revealed by Prince Sultan bin Salman, President of the Saudi Arabian Tourism and National Heritage Commission, at the Tokyo National Museum. The Japanese museum houses an exhibit exhibiting old Saudi artifacts.
In the statement made by the prince, it was stated that the footprints were based on about 85,000 years ago. Archaeologist Huw Groucutt works in the region and says researchers still analyze footprints and plan to publish an article in the coming months.
The clues provided by archaeologists for human footprints are not the first. In 2006 there were 700 fossil footprints of 20,000 years old in Australia and 13,000 footprints were found on the western coast of Canada in March
If scientists find that their footprints were made in an ancient history dating back more than 80,000 years, it would coincide with the same date as a human finger bone near a lake called Al Wusta near an old Saudi Arabia shore.
A study of the finger bone that was published last month revealed that it belonged to a man who lived 88,000 years ago. This finger bone was found in the area of an old freshwater lake just like the footprints.
Footprints contribute to evidence that the Arabian Peninsula may be an important step for people who first abandoned the African continent. The traces of humans appear in East Africa about 200,000 years ago, but the mass migration from the continent was thought to have occurred some 60,000 years ago. More recent findings indicate earlier migration (such as the 180,000-year-old jawbone found in Israel earlier this year).
It is not clear how many people migrated towards the Arabian peninsula. This vast and sandy region is a lush grassland 80,000 years ago. Until today, there were evidence of animals such as thousands of ancient lakes and water mammals in the region.
Archaeological finds have emerged in nearly 80% of the 200 ancient lake areas that archaeologists have visited so far. Among the finds are pieces of stone tools.
Archaeologists expect Saudi Arabia to become an increasingly important place to understand old human migration. The country has recently begun to allow foreign scholars to dig archaeological sites.
Petraglia says that the old archaeologist team who works here plans to continue to work in the old lakes, and as a result will expand their work caveat.
