new Delhi: How did the human species Neanderthal become extinct from Earth? Scientists have found the answer to this question. In a new study by a team of international scientists, it has been claimed that this may have happened due to the ending of the magnetic field of the Earth and the reversal of the poles.
Actually, this incident (Laschamp Excursion) happened 42 thousand years ago and for almost a thousand years, exactly the same situation remained. At the same time, scientists estimate that this event occurs at an interval of 2 to 3 lakh years. Scientists suspect that as the Earth’s magnetic field is weakening, it may be that the time for the poles to turn is coming closer.
Why is the Earth’s magnetic field important
Significantly, the Earth’s magnetic field makes life possible for humans and other organisms. It protects the ozone layer from harmful rays coming from the sun such as solar wind, cosmic res and harmful radiation. Also, weakening magnetic field long before the finish can cause major damage.
Dramatic climate change
It has been said in the study that the change in poles must have had dramatic results 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 up of Australia. Looks like.
Neanderthal started living in caves
According to scientists, due to this terrible change, Neanderthals were hiding in human caves to avoid bad weather. Due to this adverse situation, rivalry among our ancestors must have started and eventually they became extinct. Researchers enlisted the help of Radiocarbon Analysis for their study. On studying the material found from all over the world, scientists noticed that when the amount of carbon-14 was increased, the environment was undergoing major changes at the same time.
Earth towards destruction
According to scientists, the Earth’s poles change every 2 to 3 lakh years. Some scientists have said that the magnetic field of the Earth is getting weaker and due to this the time for the poles to turn is coming closer. However, many scientists also deny this apprehension. Alan Cooper of the South Australian Museum says that it is not necessary that the poles will turn again, but if that happens it will be disastrous.
