Some effects of cosmic catatrophes

“… cosmogenic isotope data suggest that 41,000 years ago a supernova exploded about 200 light-years (60 parsecs) from Earth. Initially, a flash of lightning lasting a few seconds would have dazzled observers, even with their eyes closed, on one side of Earth facing the supernova. The experience would have been much like that of a Hiroshima survivor, except that no blast wave followed.

Instead, the sky burst into an array of colours as the enormous wave of cosmic rays lit up the atmosphere. A new giant star, larger than the moon, appeared in the sky, visible night and day, and became increasingly brighter for twenty-one days as the cloud of dust ejected from the supernova expanded and thinned.”

“The remnants of the supernova remained visible in the night sky for about a decade, growing dimmer as it faded from view.”

“The era around 40,000 years ago was a period of major changes in the evolution of mankind. Neanderthals began to decline, and Cro-Magnon people mysteriously evolved into modern humans. … In addition, a mutation in human brain size appeared at that time that coincided with the emergence of traits such as art and music, religious practices, and sophisticated tool-making practices.”

“Major changes in species, including humans, occur through mutations, and the high cosmic ray rate from the supernova would have accelerated the mutation rate dramatically. One example which appears to bear this out is the evolution of blood types in human beings. Our early ancestors had only type O blood.”

“DNA evidence suggests that B type blood probably originated in Central Asia or Africa, where the percentage is uniformly highest.” … “For type A blood, the picture is more complicated, with apparent origins in Europe, Canada, and Australia.” … “Although type O blood is common everywhere, it is nearly universal among natives of South and Central America, and much more common in North America than in Asia or Europe.”

“The supernova may have a link to at least two of the races, Asian and Caucasian, as suggested by Nei (1982) and Gong and associates (2002). They presented genetic evidence showing that the two races split off from each other about 41,000 years ago, meaning that some major mutation occurred at that time.”

“… intense radiation is capable of producing the major mutations that account for the skin colour we see in the Asian and Caucasian races.”

“… at the time of the mutation, art, music, and advanced tool-making suddenly appeared to flourish, suggesting that there was a direct connection.”

“That brilliant burst of radiation silently re-arranged humankind’s DNA and unleashed a burst of brilliant cultural creativity that progressed from launching innovative new mammoth spears to launching innovative new rockets to the moon.”

Comment: Is there not a difference between creating new tools enabling survival, and technological tools directed to exploiting any minerals which may be found in outer space or, worse still, to exercise control of fellow humans on Earth who are ‘not us’ but ‘them’?
