This dangerous asteroid is thought to have struck the North of Greenland at some point in the history of Earth, which is known as the Younger Dryas. This crash started a global cooling, which was mostly felt in North America, South America, and Europe. Scientists from South Africa think that this collision was the reason behind the mass extinction of the species from the end of the last ice age. We are talking about the Pleistocene Epoch. The thing is that such an impact could also happen in the future, even if the probability is low right now. All the discovering were published in the journal called Palaeontologia Africana.
Francis Thackeray, a professor from the University of Witwatersrand, Johannesburg stated that the discovery works hand in hand with the Younger Dryas extinction theory. The findings are supported – at least partially – by the Younger Dryas Impact Hypothesis. He also said that we need to find out more about the idea of an asteroid changing the climate on a global scale and getting rid of entire species of animals. The professor was the leader of a team of researchers in Limpopo Province, in South Africa.
There, scientists found a “platinum spike” in the geological samples, which is dated back 12,800 years. These samples were found to come from a giant meteor, which was rich in precious metal. Scientists also believe that this asteroid may have had an indirect impact on human settlements all across the continent of Africa. They are not quite sure yet, but this cosmic impact could have actually affected humans because of the local changes in the environment and the ability to find food.
