People have wondered if there is life on Mars or ever has been but a new report suggests that we might all be Martians.
COULD LIFE REALLY HAVE STARTED ON MARS, NOT EARTH
Reports have suggested that there is evidence building up that life on Earth may have begun on Mars. Steven Benner from the Westheimer Institute for Science and Technology thinks that life may have arrived on Earth onboard a meteorite. But just what might have brought this odd conclusion to light?
Scientists had found an oxidized type of molybdenum, an element which might have been a crucial factor in the origin of life on Earth, which was most likely on the surface of the Red planet a long time ago when it was on Earth.
EARLY EARTH DID NOT HAVE MUCH OXYGEN, BUT MARS DID
Benner said that it is when the molybdenum becomes highly oxidized that it can then have an influence on how early life is formed. The type of molybdenum might have been around on Earth when life began as three billion years ago the surface of the Earth did not have much oxygen, while Mars did. This is another piece of evidence that seems to make it likely that life actually began on Mars and arrived on Earth thanks to a Martian meteorite, instead of life actually having started on Earth.
Organic compounds are said to be the building blocks of life, however, to turn the molecules into a substance like tar they need energy. This is when the oxidized molybdenum comes in, and Boron would be able to accomplish that.
Benner went on to say that recent analysis of a meteorite from Mars revealed that there was Boron on Mars and scientists believe that molybdenum in oxidized form was also there too.
EARLY EARTH WAS MOST LIKELY COVERED WITH WATER
There is another factor that seems to support the theory, and this is that early on Earth was most likely covered completely with water, while on ancient Mars there were many dry regions. The liquid on Earth would, therefore, have made it extremely difficult for boron to have formed in concentrations that would have been high enough when life was evolving at first. Water also causes corrosion to RNA, and this was thought to be the first genetic molecule.
Benner concluded that it was lucky that life did end up on Earth as it has been better than Mars for being able to sustain life. He said that if hypothetical ancestors had stayed on Mars, we might not have survived to tell the story.
