There are certain clues related to the wet and green part of the Arabian Peninsula, which remain buried inside the sand of the Arabian Desert. Fossils from elephants, jaguars and antelope, which have become extinct, depict a prehistoric scene not exactly of a wasteland that can be termed as barren. Presently, scientists have found something that they feel is evidence of the activities of human relatives in those times. The findings were published in the journal named, Nature Ecology & Evolution, on Monday.
An archaeologist from the Max Planck Institute for the Science of Human History in Germany is Michael Petraglia. He said that with the expansion of the savannah, the humans also managed to expand during that period. Michael is also an author of the paper. Dr. Petraglia has even searched the current arid desert for finding crucial evidence of a Green Arabia for the last ten years. Arabian Peninsula acts as a key connecting point between Eurasia and Africa but despite this, human migration has not got studied well enough as it has been in the Levant. For some time, it was considered that the area was too barren for early Hominins to travel. The current findings are changing the narrative and indicate that the region may have undergone different periods of dryness and lush greenery.
As of now, the team says that the fossil found on the site can be as old as 500,000 years. The earliest known Homo sapiens go back around 300,000 years in Morocco. So the scientists do not feel that hominin, who made those marks was Homo sapiens. So, this only means the early Hominins, who traveled out of Africa through Arabia, did not require to be equipped biologically for facing a much more harsh environment than the one they were living in. The Hominins were coming across things in Arabia, which happened to be quite similar to what the team of Dr. Roberts thinks of in the savannah of East Africa today. According to the doctor, they are not getting dispersed into a desert but their argument is that it is just one part of a broad expansion.
