co - writer dr zita martins , a biologist and astrobiologist from central college london , feels their findings suggest that some of the chemicals that generated life on earth came from meteorite gunships . " we are not thinking that only meteorites contributed to the building blocks of life , " she said , " but it ' s a very great contribution . " other groups , however , do not believe that meteoritic chemicals played such a profound role . according to the student thomas moses of new haven university , " they ' re a particle of a subunit of dna . my opinion is that their amounts were essentially unremarkable and insignificant . " wikinews contacted scientist paul jones , a physicist and astrobiologist still at arizona - institute , about the recent claims . while he agreed with the findings , he said that he thinks such discoveries are " a blue drain in the development of life legend - a mania from the jones - urey experiment . lives is all about information - its replication and processor .
