Microorganisms in the subsurface seabed on evolutionary standby
Mon, 20 Mar 2017 09:36:43 EDT
Through genetic mutations microorganisms normally have the ability to develop new properties over a short time scale. Researchers now show that microbes in the deep seabed grow in slow motion with generation times of up to 100 years.
