‘Azulian’ India conducted the youngest population of human ancestors: study


The population of ancient humans using Azulian stone tools was in India until about 177,000 years ago, shortly before the early expansion of our own species, Homo sapiens, Across Asia, according to a study released Wednesday.

The tradition of making a prehistoric instrument known as the Achaeolian is characterized by distinctive oval and pear-shaped stone fissures associated with the Handax and Homo erectus. Homo hydelpergensis.

Recent research led by the Max Blank Institute for the Science of Human History in Germany has revisited a key Achilles site at the edge of the monsoon zone in the Thar Desert of Rajasthan.

The study was published in the journal Scientific reports, Showing the existence of the Azulian population throughout Asia until about 177,000 years ago, shortly before the initial expansion of Homo sapiens.

The timing and path of the early extinctions of our own species throughout Asia has been the subject of considerable debate. However, growing evidence suggests Homo sapiens Many of our closest evolutionary relationships are related to people, the researchers said.

Identifying where these different peoples met is very important to reveal the human and cultural landscape that the early members of our race met to expand beyond Africa, they said.

Although fossils of ancient humans are very rare in South Asia, the researchers noted that changes in the stone tools they created, used and left behind can help determine when and where they occurred.

Recent research reports a relatively recent invasion of the Singi Talao site by the Athenian people 177,000 years ago.

The site was once considered one of the oldest Azulian sites in India, but now appears to be one of the youngest sites, researchers say. These dates show that the Achuveli people continued to survive in the Thar Desert after their disappearance 214,000 years ago in East Africa and 190,000 years ago in Arabia.

This study explains the environmental conditions that allowed the Azulian people to grow on the edge of the monsoon in the Thar Desert until at least 177,000 years ago.

“It supports the evidence from around the world, and India has conducted a younger population using Assyrian tools from around the world,” said Zimbabwe Blinghorn, the study’s leading author at the Max Planck Institute for Science on Hymns. “Critically, the late position of the Assyrian in Singi Talao and elsewhere in India directly presents evidence for the emergence of our own species, Homo sapiens, as it expands across Asia,” Blinghorn added.

The site of Singi Tala, located on a lake near the modern city of Tidwana on the edge of the Thar Desert, was excavated in the early 1980s, revealing several stone tool assemblies, the researchers said.

The largest crowd shows a focus on the typical stone handles and split production for Achuvelian. However, the techniques needed to accurately track these assemblies were not available at the time they were discovered.

“The lake system has excellent security conditions for an archaeological site, which allows it to return 30 years after the first excavation and re-identify key occupation boundaries,” Blinghorn said.

Researchers have used fluorescent methods to directly date sedimentary boundaries occupied by ancient humans. These methods rely on the ability to store and release energy induced by the natural radiation of minerals such as quartz and feldspar, which allows scientists to determine the last exposure to sedimentary light.

“Ours is the first study to directly identify the frontiers of occupation in Singi Tala, how these industries compare to other sites throughout the region when ancient humans lived here and formed stone tool assemblies,” said Julie Durgan. University of Oxford in the UK.

The Thar Desert is located on the western edge of the modern Indian summer monsoon system, and its livelihoods for ancient human populations may have fluctuated considerably. The researchers studied plant microfossils called phytoliths and features of the geochemistry of the soil to reveal the site’s environment at the time the Azulian instruments were made.

“This is the first time in India that the ecology of an Achaemenid site has been studied using these methods, revealing the vastness of the landscape inhabited by these people,” said Hema Achuthan, a professor at Anna University in Chennai who participated in the excavations. On the site. “The results of the two methods we used complement each other and reveal a landscape rich in grass varieties that thrive during the advanced summer monsoon seasons,” Achuthan said.
