100 million-year-old life forms found on the ocean floor.

        

       Scientists revive 100 million-year-old microbes from the sea. Japanese scientists say they have revived microbes that were in a dormant state for more than 100 million years. The tiny organisms had survived in the South Pacific seabed - in sediment that is poor in nutrients, but has enough oxygen to allow them to live.

             Found in clay samples by folks aboard the JOIDES Resolution research ship, the microbes survived almost 80 metres beneath the sea floor, underneath an astonishing 5.7 kilometres (3.5 miles) of water.

After retrieving the microbes from the sediment, Dr Yuki Morono from the Japan Agency for Marine-Earth Science and Technology incubated the microbes for a year and half. The microbes initially contained ten different major types of bacteria, but during incubation, they grew and diversified.  

The organisms the team isolated require oxygen to survive, and traces of the life-giving gas were found in the sediment. Even so, with no access to sunlight or any type of nutrient, the survival of microbes on the ocean floor is astonishing. 

For scientists, the microbes' ability to survive in ancient, energy poor environments is the most interesting part of the find. 

"The most exciting part of this study is that it basically shows that there is no limit to life in the old sediments of Earth's oceans,"  Steven D'Hondt, co-author of the study, told ABC.

Life... uh, finds a way.
