New Study Provides More Evidence, That Life Was Brought to Earth, via Meteorites.<br />A new study of several carbon-rich meteorites <br />has contributed to the theory that the building <br />blocks of life arrived on Earth from space. .<br />ScienceAlert reports that the study was led <br />by scientists from Hokkaido University in Japan. .<br />Three different meteorites <br />were the focus of the study:.<br />The 1969 Murchison meteorite <br />recovered from Australia.<br />the 1950 Murray meteorite <br />which landed in Kentucky.<br />and the Tagish Lake meteorite which was <br />recovered in British Columbia in 2000.<br />The team detected organic compounds that form <br />the very backbone of the nucleic acid molecules <br />found in all life on the planet, DNA and RNA. .<br />Researchers suggest that approximately 4 to 3.8 billion years ago <br />a diverse range of these building blocks could have been <br />delivered to our planet via similar meteorite strikes.<br />ScienceAlert reports that this theory will be further investigated once sample missions to asteroids Ryugu and Bennu provide more extraterrestrial material to examine.<br />ScienceAlert reports that this theory will be further investigated once sample missions to asteroids Ryugu and Bennu provide more extraterrestrial material to examine.<br />These samples will give scientists an even better <br />chance of determining whether these molecules <br />could have been brought to Earth by meteorites. .<br />The team's results were published <br />in 'Nature Communications.'
