Thanks Cataclysm, for Blue Eyes
Further (minor) evidence for my evolution circa 10,000 BC theories:
A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6,000 and 10,000 years ago. Before then, there were no blue eyes.
…”From this we can conclude that all blue-eyed individuals are linked to the same ancestor,” Eiberg said. “They have all inherited the same switch at exactly the same spot in their DNA.” Eiberg and his colleagues detailed their study in the Jan. 3 online edition of the journal Human Genetics.
That genetic switch somehow spread throughout Europe and now other parts of the world.
“The question really is, ‘Why did we go from having nobody on Earth with blue eyes 10,000 years ago to having 20 or 40 percent of Europeans having blue eyes now?” Hawks said. “This gene does something good for people. It makes them have more kids.”
Unless of course multiple people had the same mutation during the last cataclysm. My theory postulates that during a massive influx of cosmic rays, human DNA chose which mutations to repair, and which to leave be. I suggest that our DNA is happy to experiment with such things as size and colour – things that should not affect our function much, if at all.
