Scientists at NASA's Curiosity Rover have found a type of carbon that on Earth is associated with biological processes from several powdered rock samples collected from the surface of Mars.

While the finding is intriguing, it doesn't necessarily point to ancient life on Mars, scientists said they have not yet found conclusive supporting evidence of ancient or current biology there, such as sedimentary rock formations produced by ancient bacteria, or a diversity of complex organic molecules formed by life, according to a NASA statement.
