Very interesting information indeed. Somewhere in his last book 'Brief Answers To The Big Questions', Stephen Hawking wrote that it is likely,due to the advances in genetic engineering, that in the next millennium scientists will be able to redesign human DNA completely. There would be probably legal prohibitions against its implementation due obvious ethical reasons but on the other hand a thousand years ago mankind had very different morals regarding society, compared with what we consider right and what we consider wrong today. Maybe science will prove time is an illusion...
