Stephen Hawking: Humans are "Entering a Stage of Self-Designed Evolution" - - 20100329

[...] In the last ten thousand years the human species has been in [...] "an external transmission phase," where the internal record of information, handed down to succeeding generations in DNA, has not changed significantly. "But the external record, in books, and other long lasting forms of storage [...] has grown enormously. [...] [they] would use the term, evolution, only for the internally transmitted genetic material, and would object to it being applied to information handed down externally. [...] our human brains "with which we process this information have evolved only on the Darwinian time scale, of hundreds of thousands of years. [...] But we are now entering a new phase [...] "self designed evolution," in which we will be able to change and improve our DNA. "At first [...] these changes will be confined to the repair of genetic defects [...] I am sure that during the next century, people will discover how to modify both intelligence, and instincts like aggression."
