Life may have developed on Mars, not Earth, scientist says
All life on Earth could be alien life. So suggests Professor Steven Benner, who presented his thesis that life in our solar system may have developed not on our blue planet, but on Mars.
“The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,” he told the BBC.
The surprising idea was presented by Benner — from the Westheimer Institute for Science and Technology in Gainesville, Florida — at the Goldschmidt conference in Florence. (AP Photo/NASA)
