Earth life 'may have come from Mars'
By Simon Redfern
Reporter, BBC News, Florence
Life may have started on Mars before arriving on Earth, a major scientific conference has heard.
New research supports an idea that the Red Planet was a better place to kick-start biology billions of years ago than the early Earth was.
The evidence is based on how the first molecules necessary for life were assembled.
Details of the theory were outlined by Prof Steven Benner at the Goldschmidt Meeting in Florence, Italy.
Scientists have long wondered how atoms first came together to make up the three crucial molecular components of living organisms: RNA, DNA and proteins.
The molecules that combined to form genetic material are far more complex than the primordial "pre-biotic" soup of organic (carbon-based) chemicals thought to have existed on the Earth more than three billion years ago, and RNA (ribonucleic acid) is thought to have been the first of them to appear.
Simply adding energy such as heat or light to the more basic organic molecules in the "soup" does not generate RNA. Instead, it generates tar.
RNA needs to be coaxed into shape by "templating" atoms at the crystalline surfaces of minerals.
The minerals most effective at templating RNA would have dissolved in the oceans of the early Earth, but would have been more abundant on Mars, according to Prof Benner.
This could suggest that life started on the Red Planet before being transported to Earth on meteorites, argues Prof Benner, of the Westheimer Institute of Science and Technology in Gainesville, US.
The idea that life originated on Mars and was then transported to our planet has been mooted before. But Prof Benner's ideas add another twist to the theory of a Martian origin for the terrestrial biosphere.

Your gratuitous and pointless slap at Timmy is pointless and gratuitous.
I'm at work, and unlike some Languishtistas that means I'm busy.
OH SNAP TIMMAY DROPS THA HAMMAH

You posted, ergo. :P
Another non-story puffed into a misleading story by the BBC. The theory isn't new, and the Goldschmidt Conference (not " Goldschmidt Meeting") isn't a "major scientific conference."
Some new theoretical data got presented to an industry meeting. Woopie.
Thanks, Tim, for not bothering with this trivia.
Yeah, this theory was around when I was a boy.
Nevertheless, even if early earth life came from Mars, we still wouldn't be extraterrestrials. The distant ancestor is a landed immigrant, and we're as earthly as mom or apple pie. Your nativist thinking is a sign of a deep racism, and you should be ashamed of yourself. You might as well just go stand on the streetcorner and shout 'wog' at passers-by.
This has been around for decades. Although it was often comets carrying the seeds.

He swings, he misses.
Doesn't need a new thread so posting in this one.

Dark Side Of The Moon ?
We can't see it. The dark side of the moon.

It's called dark for a reason.
I can't make out what land mass that is.

That is brilliant.
Nice animation on the nasa site too
This is not a new theory at all.
