What did you find inside?
In the new study, it has been confirmed to have found tools made by humans around 20 million years ago. Along with this, it is believed to be the oldest evidence in the world of living in a cave. Evidence of using fire has also been found here. “Wonderwork is unique among ancient Oldowan sites,” said study lead lead professor Ron Schar. Here the team searched in layers of caves and further found Oldwood tools with hand-made axes. (Photo: Michael Chazan)
How did the time change?
Here they found evidence of using fire 10 million years ago. Burnt bones, sediments and tools have been found here. The team analyzed an 8-foot-thick sedimentary layer in which stone tools, animal remains and fire-related items were found. Their magnetic signal has been studied. Magnetization occurs when the particles of wet clay, which have come from outside into the cave and have remained on the ancient ground, and this shows the direction of the magnetic field of the Earth at that time.

In the lab analysis, it has been found that some samples were magnetized towards the south, which is today’s magnetic field. Shar has said that the time for the Earth’s magnetic poles to turn is considered world-wide. This gives a significant evidence of the order of the layers inside the caves. Professor Ari Mateman has confirmed with the help of the Secondary Dating Method that the oldest primitive human beings must have been here. He told that the quartz particles in the sand make a geological clock that moves as it goes inside the cave. These can be identified with the help of different isotopes. (Photo: Michael Chazan)
