So-called "Cradle of Humanity" reflects the change in the early climate – Xinhua


On Thursday, a team of international researchers, including Australian researchers, made a clearer understanding of how and how our ancestors knew how and when they were. .

The fossil record, known as the Cradle of Humanity, has long been recognized as Africa's birthplace and corresponds to the cave in South Africa.

However, scientists have struggled to create a real-time timetable for fossils due to a lack of methods.

Professor Andy Herr of the University of Lo Trough said that "showing South Africa as a starting point for mankind as a cave's complexity and their difficulties has left a record for it."

"In this study, currents flows in different caves of the same time as the volcanic layers of the East, showing that it allows them to link their sequences and fossils with regional sequences," he said.

The World Heritage, the cave of the Cradle of Humanity, has produced about 40 percent of all of mankind's famous works, including the famous Australopithecus African bone, Ms. Ples.

Robin Pickering, a leading researcher at the University of Cape Town, says the group's acquaintance "illustrates the age of all the excavations in the region" and describes the climatic conditions of our ancestors.

"The key to rock stones," said Picker.

Flowing stones are calcite or other carbonate minerals that are formed when water is turned into caves.

"We know that caves are growing in the caves of currents, and when the rain is high, we get to know the rocks, and we have chosen this time of rainfall," said Pickering.

Using the advanced uranium methods developed at the University of Melbourne, the group analyzed a 28-storey stone layer that ran between the rich sediments on the eighth floor of the eight caves – 6 and 1.3 million years ago when discovering the fossils.

"We know that during this time, when the cave was open, the climate was dry and it is similar to what we have now," he said.

Experts believe that this is a stunning breakthrough in the history of mankind and the great contribution to the understanding of the lives of our common ancestors.
