The ancient earth was a much more hostile place than today. About 42,000 years ago, the earth saw its magnetic poles rotate. Scientists know that the earth’s magnetic poles have been reversing since the late 1960s. The magnetic poles are not static. The poles are generated by electric currents from the planet’s liquid outer core that are constantly in motion.
It is believed that the last wicketkeeper had a major environmental impact. However, the magnetic field has weakened, causing more cosmic rays to reach the planet’s surface. Despite the fact that more cosmic rays have been bathed, they are unlikely to have a significant impact on plant and animal life. However, a new study has found that the additional cosmic increase may decrease ozone concentrations and allow more ultraviolet radiation through the atmosphere.
The researchers believe it has contributed to changing weather patterns that could extend the ice sheet across North America as Australia dries out. This could have caused the extinction of many large species on the planet. The authors of the study also believe that a solar storm could have driven old people into the caves for shelter. According to the study, competition for resources between remaining species may be the reason why Neanderthals are dying out.
Until now, scientists could not agree on what led to the extinction of the Neanderthal. Some previous research has suggested that the extinction occurred naturally as a result of inbreeding with modern humans. Others believe that Neanderthals could compete for resources as modern humans began to increase in numbers. Researchers on the new study believe it is no coincidence that the Neanderthals immediately became extinct after a major shift of the planet’s magnetic poles.
Researchers have turned to the ancient kauri tree that lived during the Neanderthal people who looked to its rings for recording radiocarbon levels. The rings provided evidence of increasing radiocarbon when the magnetic fields turned around, known as the Laschamps outing. The team believes the event could have contributed to the downfall of the Neanderthals, but they acknowledge that it is difficult to know exactly when they died.
