One of the mysteries of DNA is how we can share so many genes with chimpanzees, and yet be so different from them. Now scientists say this has to do with which genes have been “turned on.” There has been speculation that chimps were intentionally altered long ago by scientists from another world, in order to create humans. While there is no proof of this, now we know how it would have been done.

In November, astronaut Mike Foale said, “It sounded like a metal tin can kind of being expanded and compressed. It was a noise that lasted about a second. It sounded like an impact or something.”
