co - author dr annemarie cummings , a chemist and astrobiologist from imperial college london , believes their conclusions suggest that some of the chemist that generated life on earth arrived from asteroids bombardments . " we are not saying that only meteorites connected to the building blocks of lives , " she wrote , " but it ' s a very important contribution . " other studies , however , do not realize that meteoritic chemicals play such a significant role . according to emeritus professor robert shapiro of upstate amsterdam university , " they ' re a subunit of a particle of bacteria . my belief is that their amounts were essentially unimportant and insignificant . " wikinews contacted dean paul jones , a geologist and astrobiologist now at arizona state campus , about the recent discovery . while he agreed with the findings , he explained that he says such discoveries are " a det herring in the origin of life story - a hangover from the miller - urey experiment . lives is all about information - its production and processors . "
