Ancient humans used to live on a reverse Earth

Volcanic data show that our ancestors spent 22,000 harsh years when the Arctic of the Earth gradually turned into Antarctica and vice versa.

Volcanic data show that our ancestors spent 22,000 harsh years when the Arctic of the Earth gradually turned into Antarctica and vice versa.

The new study led by geological science professor Bradley Singer from the University of Wisconsin-Madison (USA) has discovered a particularly long period in human history, when the Earth reversed polarity from the last time. .

The work stems from discoveries in 1993, when Professor Singer and his colleagues studied a volcano in Chile and discovered unusual ancient lava flows .

The analysis shows that strange lava flows are evidence of a two-pole reversal of the earth. It was a difficult and slow process, lasting up to 22,000 years, not 1,000 or 10,000 years as previously assumed.

Reverse polarity is the process that occurs when iron molecules in the extraterrestrial core (a layer of liquid surrounding the inner core in solid state) begin to move in the opposite direction to the other iron molecules around. them. When this "army" upstream is increased, these molecules have a strong impact on the magnetic field from the earth's core, making the planet's magnetic poles reverse.

During the 22,000 years of the Earth's reversal, the Earth's magnetic field - which is the shield that protects the planet from heat and radiation from the sun - has been weakened, making the lives of creatures much more difficult. Many, including our ancestors.

Estimated, the last polarity reversal of the earth occurred about 773,000 ago. At that time, Homo Sapiens (wise people or modern people, us), the only representative of the human genus that has survived to this day, has not yet appeared. However, the ancestors of the extinct species of the genus were born and lived in the "cradle" of Africa millions of years before.

Commenting on the work, geophysicist John Tarduno of the University of Rochester (USA), who did not participate in the study, said: "The actual effect of that is still controversial, and they are not tragic. extreme as many have predicted ".

There have been studies showing that the earth has reversed polarity many times in 2.5 million years, and the next reversal will soon arrive in a few thousand years. Many people fear that it may be the end of the world with humankind. But according to these new data, the last reversal does not cause the end of the world.

Singer argues that the possible effects on polar earth are gene mutations , stress for some plants and animals, in which some species may become extinct due to inadequate adaptation. of the sun's harmful ultraviolet rays. Thankfully, the ancestor of the genus has gone through a difficult period, continues to proliferate and evolves into many new species, including us.

In today's context, polarity reversal can also damage many communications systems. Recently, scientists have also discovered a slight change of the north pole: from North Canada, the Arctic today has "run" to the position of Siberia (Russia).
