co - author dr zita martins , a professor and astrobiologist from imperial collegiate london , claims their finds demonstrate that some of the chemicals that generated life on earth contributed from crater bombardments . " we are not telling that only meteorites contributed to the building waves of life , " she stated , " but it ' s a very great result . " other scientists , however , do not believe that meteoritic chemicals playing such a significant part . according to adjunct director bob shapiro of new york universidad , " they ' re a fraction of a subunit of dna . my opinion is that their claims were wholly unimportant and insignificant . " wikinews contacted professor paul hughes , a physicist and astrobiologist residing at alaska state institution , about the recent finds . while he agreed with the hypothesis , he said that he thinks such discovery are " a blue herring in the origin of life legend - a hangover from the scott - urey experiment . life is all about innovation - its development and synthesis .
