Scientists have discovered why mankind started to get cancer.
The reason is called the explosion of two supernovae, radiation which reached the Earth and adversely affected the health of primitive people.
About two million years ago in the history of our planet was an incident that, according to some researchers, could be the emergence of the ancestors of human cancers. The reason is called the explosion of two supernovae, radiation which reached the Earth and adversely affected the health of primitive people.
In those days the world was actively developed Homo erectus (Homo erectus), it was the kind that began to walk on two legs to produce the first and the most primitive tools. Supernova, according to scientists, exploded at a distance of several hundred light years from Earth, it was far enough away not to destroy all life on the planet, but close enough to reward the Earth with a portion of the radioactive isotope iron-60.
Primitive people who witnessed this cosmic phenomenon, could see a very bright object, outshining all other lights, thereby violating for many years, the cycle of daylight. According to research, these explosions was the fact that the background radiation on the Ground three times exceeded the norm.
It is believed that this could cause the primitive human cancer, which to this day suffers from a large number of people. However, according to some experts, this statement is quite controversial, as today in some places of the planet radioactive contamination 20 times higher than the accepted norm, and the astronauts for a long stay on the ISS, and thirtyfold does receive a portion of the radiation.
