Don't know that it's very weird at all. Our DNA does not remain stagnant and can and will be altered by a surprising number of things (and the list of known mechanisms of change grows every day). |
| The problem with having an open mind is that people keep trying to put things in it. | |

Oopsie... We Were Totally Wrong About That Scott Kelly Space Genes Story On Monday (March 12), we published a story about astronaut Scott Kelly returning after a year in space with big changes to his genetic code, so much so that he was no longer his brother's identical twin. It turns out we got the story wrong in a big way. In the original story, we reported that 7 percent of Kelly's genetic code had changed after his stint in space. But that enormous level of genetic change would mean Kelly went to outer space and came back a space alien: All humans share more than 99 percent of our DNA, and we share more than 98 percent of our DNA with chimpanzees, our closest living relatives. That divergence in chimp versus human DNA comes from roughly 40 million mutations in the base-pairs, or letters, that make up the genetic code, Live Science previously reported. By contrast, in a press release from NASA, researchers reported hundreds of unique mutations in the DNA of both Scott and Mark Kelly (his identical twin brother). That's more than would be expected, but nowhere near enough to make the duo "no longer identical twins." In reality, identical twins that are both Earth-bound would also rack up mutations over the course of their lives; identical twins ordinarily don't have perfectly identical genomes. |

So glad the Science (reporting) was settled. |

What does "gene mutation" mean? There are millions of copies of the DNA in a body - are they all changed the same way? That's hard to believe. |
