Geomicrobiologist Yohey Suzuki of the University of Tokyo finds living microbes in 2 billion-year-old rock.

Microbes in isolated underground pockets like these tend to evolve more slowly, since they're detached from many of the pressures that drive evolution in more populated habitats.

This suggests that underground microbe communities still alive on Mars , surviving long after the water on the surface dried out.
