Contained here within are discussions regarding the discovery made by scientists regarding bacteria from rocks from Earth that have a closed similarity to bacteria that were uncovered from the Martian meteorite. According to a research group of NASA, the bacteria that have grown in chambers, which imitated natural growth conditions underneath the surface of the Earth, have shown an amazing likeness to characteristics observed in an organism that can be considered as probable primordial life seen in billions of years old Martian meteorite.

Numerous bacteria gathered from deep underground in Washington State not only raised and procreated in the laboratory chambers but also died and fossilized in a span of eight weeks. A few of these earthly bacteria and their parts known as filaments were fossilized and were incredibly comparable to some of the characteristics earlier unraveled as probable fossilized Martian organisms. Numerous fossilized varieties grown in the laboratory experiments are noticeably alike in size and shape to characteristics the researchers have observed in 1996 in Martian meteorite. It is also stated in the article the research study performed two years ago wherein the characteristics of the meteorite may possibly indicate primordial life on Mars, the tiny sizes and shapes of the probable fossilized details caught substantial criticism due to zero data reported in the earlier geologic locations on Earth.

The mean sizes of the microorganisms discovered in the rocs of the Washington State are well within the scope of sizes viewed in worldly bacteria. The researchers asserted that the cell leftovers in micron sizes range that were created when cells died and decomposed, may possibly be fossilized inside the rocky pools of water underneath the surface of the Earth. Several of these fossilized organisms seemed to be hollow due to minerals that were left on the most external side of walls of the organisms. Once the cell walls are debased they can not be detected anymore, retaining only a hollow structure comprising of minerals.

In the history of the red planet, which is Mars, there seemed to have been a rich supply of water on and underneath its surface, which is why the observation of mineralized fossils in underground pools on Earth might be significant to Mars. The Martian meteorite is alleged to have derived underneath the Martian surface and to have been expansively broken by impacts as meteorites showered the planets in the primitive internal solar system. Water is alleged to have infiltrated fractures in the subsurface rock probably creating an underground water system at the time in between 3.6 to 4 billion years ago. The said underground Martian water system may perhaps been the most excellent place for life during the large extent of the history of Mars.

In the research study about thirty percent of the cells produced in the laboratory had joint appendages. Further, there were filaments that were not connected to cells probably bacterial appendages that were mineralized. The chemical structure of these detached mineralized appendages, which is way too small than normal bacteria, are almost the same to the mineralized organisms. The researchers suggested that the mineralized portions may possibly be uncovered in the fossil data in the rocks of the Earth and should be hunted alongside with the entire bacteria in primitive rocks. The identification of biological characteristics changed by the existence of minerals is essential in deciding whether particular characteristics in earthly rocks and in meteorites may perhaps have a biological source.
