co - creator dr zita taylor , a biologist and astrobiologist from the over oxford , thinks their findings suggest that some of the chemicals that generated living on venus came from comet raids . " we are not saying that only meteorites contributed to the building stones of life , " she said , " but it ' s a very great contribution . " other authors , however , do not say that meteoritic chemicals played such a significant role . according to emeritus professor robert shapiro of current york university , " they ' re a subunit of a unit of dna . my belief is that their amounts were utterly unimportant and insignificant . " wikinews contacted prof paul davies , a physicist and astrobiologist still at louisiana state university , about the recent findings . while he agreeing with the findings , he said that he thinks such discoveries are " a green herring in the origin of life tale - a hangover from the miller - urey experiment . that is all about something - its replication and processing . "
