The survey alleges an asteroid impact that triggered the "Younger Dryas" episode in the Earth's history as temperatures plummeted. This has been linked to the extinction of many animals, including giant sloths in South Africa and mammoths in Europe.
Around the same time, the Clovis people, an early North American culture, disappeared from the records.
Similar disappearances took place in Africa during the period, indicating a catastrophic global event.
A team of scientists believe that platinum deposits excavated in Wondercrater, South Africa, support asteroid impact theory around the world.
The deposits indicate that high platinum content dust was raised 1
The temperatures on the earth dropped between 12.800 BC. Chr. And 11,700 v to an asteroid impact.
The study was published in the journal Palaeontologia Africana.
Professor Francis Thackeray, part of the team behind the report, commented, "Our findings support, at least in part, the highly controversial hypothesis of the Younger Dryas Impact.

a significant part of the then species on Earth, including dinosaurs.
Professor Thackeray commented on his research as follows: "We caution that these technological changes in North America and the African subcontinent are about the same. This could be indirectly linked to an asteroid impact with serious global consequences.
"We can not be sure, but a cosmic impact could have affected people as a result of local environmental changes and the availability of food products that are associated with sudden climate change. "
In November 2018, scientists in Greenland found a 19-mile asteroid impact crater.
There is speculation that this could be the asteroid D, which triggered the global temperature drop of the younger Dryas.
However, most scientists blame changing the oceanic circulation systems of the younger Dryas, rather than an asteroid.
