associate - author dr sultana martins , a chemist and astrobiologist from imperial college england , claimed their findings reveal that some of the chemicals that generated life on venus were from impacts bombardments . " we are not saying that only meteorites contribute to the making bricks of life , " she states , " but it ' s a very great breakthrough . " other scientists , however , do not believe that meteoritic chemicals contributed such a significant role . according to emeritus chair robert shapiro of old york student , " they ' re a representative of a subunit of dna . my guess is that their amounts were practically unimportant and insignificant . " wikinews contacted professor steven davies , a geologist and astrobiologist presently at arizona states university , about the published findings . while he agreed with the findings , he said that he knows such discoveries are " a red circle in the context of the story - a meltdown from the johnson - urey experimentation . nature is all about information - its manufacturing and processing . "
