How Were The Adivasis Extinct? Scientists Got The Answer

Read Time:2 Minute, 24 Second

How did the primitive species Neanderthal become extinct from the earth? The answer to this question seems to be found. In a recent study by a team of international scientists, it has been claimed that this happened due to the collapse of the Earth’s magnetic field and the reversal of the poles. This incident (Laschamp Excursion) took place 42 thousand years ago and such conditions remained there for about a thousand years. At the same time, scientists estimate that this phenomenon occurs at a difference of 2 to 3 lakh years and as the Earth’s magnetic field is weakening, it may be that the time for the poles to turn is getting closer.

Why is the Earth’s magnetic field important?

Earth’s magnetic field makes life possible for humans and other organisms. It protects the ozone layer from the solar wind, cosmic ridges, and harmful radiation from the sun. This area is the highest at the poles but sometimes it also reverses. Not only this, much damage can be caused by a weakened magnetic field long before it ends. Due to this, there can be problems in operating the equipment. Particularly moving satellites and other craft in space may stop running. A study published in the journal ‘Science’ states that the weakening of the magnetic field caused rapid changes in the climate. Scientists believe that the occurrence of Lascamp has not been studied more specifically.

Dramatic climate change

The study says that the change in poles must have had dramatic consequences and the climatic conditions have become severe. Because of this, mammals became extinct. Professor Chris Turney has stated, ‘We see a sharp increase in the ice layer over North America during this period, the tropical rain belts in the Western Pacific appear to be changing rapidly and the belt of winds in the Southern Ocean and the drying of Australia.

Started living in caves

Scientists say that these changes caused the Neanderthals to hide in caves to avoid inclement weather. Due to these circumstances, rivalry among our ancestors must have started, and eventually, they became extinct. Researchers enlisted the help of radiocarbon analysis for their study. An increase of carbon-14 was observed in the atmosphere which is caused by cosmic radiation. On studying the material found from all over the world, scientists found that when the amount of carbon-14 was increased, the environment was undergoing major changes.

So is the earth towards destruction?

Scientists say that the Earth’s poles change every 2 to 3 million years. Some scientists have reported that the Earth’s magnetic field is getting weaker. So it is likely that the time for the poles to turn is coming closer. However, many scientists also deny this fear. According to Alan Cooper of the South Australian Museum, it is not necessary that the poles will turn again but if it happens then it will be disastrous.
