Are You A MartianCambridge MA (SPX) Mar 24, 2011 Are we all Martians? According to many planetary scientists, it's conceivable that all life on Earth is descended from organisms that originated on Mars and were carried here aboard meteorites. If that's the case, an instrument being developed by researchers at MIT and Harvard could provide the clinching evidence. In order to detect signs of past or present life on Mars - if it is in fact true that we're related - then a promising strategy would be to search for DNA or RNA, and specifically for pa ... read more |
