The excavation was told the details of the eruption of Toba supervolcano


The recently discovered archaeological sites in southern and northern India have given an idea of how people lived before and after the colossal Toba volcanic eruption 74,000 years ago.

Excavations participated an international research team of scientists from Oxford University and Indian experts.

The seven-year project was devoted to the study of the environment in which people lived, their stone tools, as well as plants and animal bones of the time. The research team concluded that many forms of life survived the super-eruption, contrary to another study from which it was concluded that a significant reduction in animal population.

According to scientists, innovative work is that the species responsible for creating stone tools related to Homo Sapiens. The analysis of stone tools showed that the artifacts belong to the Middle Paleolithic and are similar to those that create the modern African natives. "Although we are still looking for fossils of people to accurately confirm the hypothesis, we are encouraged by the technological coincidences. This suggests that the population of people over 74 inhabited India thousands of years ago, about 15,000 years earlier than previously thought until today," said Project Manager Michael Petragliya (Michael Petraglia), a senior researcher at the School of Archaeology at the University of Oxford.

The theory of the extinction of the people as a consequence of the super-eruption of Toba, is a frequent subject of scientific debate. But the fact that the Middle Palaeolithic tools of similar samples date back to the time before and after the eruption of the volcano suggests that people survived the eruption were the same people to use all of the same stone tools. According to the findings, other ancestors of modern humans, such as Neanderthals in Europe and the so-called hobbits (Homo floresiensis) in south-east Asia, also survived the eruption.

Although some scholars have speculated that the eruption resulted in the complete destruction of the environment, conducted by Oxford study suggests that the existing environmental conditions, have contributed to relatively rapid recovery.

While some bones found during the excavations Toba, but in a complex of caves Billasurgam (Billasurgam) in kurnul (Kurnool), Andhra Pradesh (Andhra Pradesh), scientists have found a deposit, which comes to the age of 100-thousand mark. They contain the bones of animals: wild animals, carnivorous predators, monkeys. Also, the remains of plants have been identified in the caves and in the plains, which gives important information about the level of damage that was caused by the volcanic eruption of Toba environment.

Dr. Petragliya says: "These exciting new evidence cast doubt on the theory of global natural disaster caused by the super-eruption of Toba. Course specific environmental harm has been done. There evidence that the ash temporarily stalled the development of plants and definitely scored and contaminated fresh water tanks, allegedly causing harm to animals and maybe even people.
