Life From Mars
Could life on Earth have been seeded by Martian life forms hitching a ride on a meteorite? Chemist Steven Benner says that crucial elements for the precursors of organisms on our planet would have only been available on Mars three billion years ago. Benner and planetary scientist Christopher McKay discuss the possibility of the Red Planet kick-starting life on Earth.
Steven Benner is a distinguished fellow at the Westheimer Institute at the Foundation for Applied Molecular in Gainesville, Florida.
Christopher McKay is a planetary scientist with the Space Science Division at the NASA Ames Research Center in Moffett Field, California.
