Research in Australia found traces of ancient life

Scientists in Australia in studies dating back 3.5 billion years 'complex microbial ecosystems' tracks reached. Discovery, the earliest life on Earth was meant to represent the instance.

Researchers in the Pilbara region of Western Australia state on the layers of rock in their research , dating back billions of years found traces of life .

Microbes , known for its ancient rock formations in the western part of the settlement called Marble Bar ' Dresser Formation ' in the rock from where specified .

Made a statement to the Guardian, Professor David Wacey from the University of Western Australia , ' findings , the oldest life forms on Earth on that date , pulling back a few million years ' , he said.

Wacey , " Pilbara region, the less deterioration in the entire world with ancient rock formations . Difficult to find structures older than the rocks here ... 3:45 billion in the past year our research we found traces of life dating back to before . This time we were able to go back a little further , "he said .

Wacey , Dresser rock from the very thin sections, identify the group stated that ancient microbes . Who prefer to live in groups of bacteria and germs , they need to have lived within the different layers of rock by chemical , light-loving situated in the upper part of the rock has been expressed .

The team has examined one of the rocks .

WORLD was covered by oceans
Ancient bacteria 3.5 billion years ago, where it belongs , in much of the world was covered by oceans and the temperature was much higher than today . The most common type of bacteria while creating life , advanced life forms had yet to emerge .

Wacey , whether it comes at a time when almost no oxygen , CO2 and methane in the atmosphere of the raid , he said .

The world is almost entirely covered by oceans days, was experiencing a lot of volcanic activity and sulfur ratio was higher in the atmosphere . Up to 2.5 billion , with the development of living nucleated cells were observed.

Pilbara rocks in rock formations on Mars , indicating that the similarity Wacey , " the study of life on a planet outside us that one day may give clue . It's pretty exciting , "he said .
