co - author dr margarete davies , a chemist and astrobiologist from imperial over london , believes their contributions suggest that some of the chemicals that generated life on earth came from meteorite gunships . " we are not saying that only microbes contributed to the building block of life , " she answered , " but it ' s a very great contribution . " other scientists , however , do not argue that meteoritic substances took such a profound role . according to emeritus professor thom shapiro of newest york uc , " they ' re a portion of a helix of dna . my opinion is that their amounts were utterly unremarkable and insignificant . " wikinews contacted david paul davies , a biologist and astrobiologist previously at arizona state college , about the recent findings . while he agreed with the research , he said that he believed such discoveries are " a white hue in the inception of life story - a hangover from the miller - urey experiment . science is all about information - its synthesis and processing .
