According to many planetary scientists all life on Earth is descended from organisms that originated on Mars and were carried here aboard meteorites.

Researchers at MIT and Harvard have developed the instrument which will provide the proof regarding this.

Following facts are already established by the scientist.

In the early days of the solar system, the climates on Mars and the Earth were much more similar than they are now, so life that took hold on one planet could presumably have survived on the other.

An estimated one billion tons of rock have traveled from Mars to Earth, blasted loose by asteroid impacts and then traveling through interplanetary space before striking Earth's surface.

Microbes have been shown to be capable of surviving the initial shock of such an impact, and there is some evidence they could also survive the thousands of years of transit through space before arriving at another planet.

Orbital dynamics show that it's about 100 times easier for rocks to travel from Mars to Earth than the other way.
So if life got started there first, microbes could have been carried here and we might all be its descendants.

In order to detect signs of past or present life on Mars — if it is in fact true that we're related — then a promising strategy would be to search for DNA or RNA, and specifically for particular sequences of these molecules that are nearly universal in all forms of terrestrial life.

That's the strategy being pursued by MIT research scientist Christopher Carr and postdoctoral associate Clarissa Lui, working with Maria Zuber, head of MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS), and Gary Ruvkun, a molecular biologist at the Massachusetts General Hospital and Harvard University, who came up with the instrument concept and put together the initial team.
Lui presented a summary of their proposed instrument, called the Search for Extra-Terrestrial Genomes (SETG), at the IEEE Aerospace Conference this month in Big Sky, Mont.

Recent Mars orbiter and rover missions have clearly shown that Mars once had abundant water, and many of the conditions thought to be needed to support life.
And although the surface of Mars today is too cold and dry to support known life forms, there is evidence that liquid water may exist not far below the surface. "On Mars today, the best place to look for life is in the subsurface

The MIT researchers' device would take samples of Martian soil and isolate any living microbes that might be present, or microbial remnants (which can be preserved for about up to a million years and still contain viable DNA), and separate out the genetic material in order to use standard biochemical techniques to analyze their genetic sequences.

the team has been developing a device that could take a sample of Martian soil from below the surface — perhaps dredged up by a rover equipped with a deep drill — and process it to separate out any possible organisms, amplify their DNA or RNA using the same techniques used for forensic DNA testing on Earth, and then use biochemical markers to search for signs of particular, genetic sequences that are nearly universal among all known life forms.

The researchers estimate that it could take two more years to complete the design and testing of a prototype SETG device.
Although the proposed device has not yet been selected for any upcoming Mars mission, a future mission with a lander or rover equipped with a drill could potentially carry this life-detection instrument.

No instrument has been sent to Mars specifically to look for evidence of life since NASA's twin Viking landers in 1976, which produced tantalizing but ambiguous results.

An instrument on the Mars Science Lander to be launched in the fall will investigate chemistry relevant to life. The instrument from the MIT-Harvard team directly addresses Earth-like molecular biology.

Very interesting but I am not sure. I do not believe we will ever find of origin of life...not with concrete proof...these are just theories..

Wow , thanks for sharing . I don't know are facts right or wrong but they look interesting .
