joint - authored dr sultana davis , a researcher and astrobiologist from oriental collegiate paris , believes their findings reveal that some of the chemicals that generated lives on earth came from asteroid airstrikes . " we are not saying that only asteroids contributed to the build blocks of life , " she said , " but it ' s a very great contribution . " other scientists , however , do not accept that meteoritic chemistry played such a fundamental role . according to emeritus professorship mark shapiro of north york university , " they ' re a subunit of a subunit of dna . my belief is that their effects were utterly unimportant and insignificant . " wikinews contacted professor paul davies , a professor and astrobiologist presently at arizona state university , about the recent investigations . while he went with the claims , he said that he thinks such discoveries are " a red herring in the end of life story - a nightmare from the miller - urey research . death is all about information - its transcription and processing . "
