Como me da risa la ciencia, primero niega y luego tímidamente va poco a poco... acercándose a lo que sin tanto aparato ya mitos o costumbres narran, ahora salen con que sí, parece que los terricolas somos marcianos.
"The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock," Steven Benner, a chemist at the Florida-based Foundation for Applied Molecular Evolution, said in a news release on Thursday.
Perhaps even more startling, Benner suggests that the conditions necessary to produce life “may still exist on Mars,” he said.
The theory hinges on the chemical element Molybdenum, which would not have been available on Earth some 3.6 billion years ago when life is believed to have first appeared. An oxidized form of the element, however, might have been abundant enough on Mars at the time to truly animate the universe.
"It’s only when molybdenum becomes highly oxidized that it is able to influence how early life formed," Benner said in a statement. "This form of molybdenum couldn’t have been available on Earth at the time life first began, because 3 billion years ago, the surface of the Earth had very little oxygen, but Mars did. It’s yet another piece of evidence which makes it more likely life came to Earth on a Martian meteorite, rather than starting on this planet."
