con - inventor dr margarete martins , a chemist and astrobiologist from imperial college london , believes their findings prove that some of the substances that generates life on earth came from meteorite barrages . " we are not said that only meteorites contributed to the building blocks of life , " she said , " but it ' s a very great breakthrough . " other experts , similarly , do not believe that meteoritic chemicals played such a significant role . according to emeritus professor robert klein of upstate york university , " they ' re a subunit of a subunit of chromosome . my perspective is that their amounts were absolutely meaningless and incomplete . " wikinews visited professor john matthews , a physician and astrobiologist formerly at arizona state university , about the original findings . while he agreed with the discovery , he noted that he thinks such discoveries are " a red fox in the origins of earth storyline - a hangover from the miller - urey experiment . life is all about it - its manufacturing and processing .
