FLASH: Women are NOT from Venus

An amazing report from the BBC:

“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 Professor 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 Professor Benner. This could suggest that life started on the Red Planet before being transported to Earth on meteorites, argues Professor Benner, of the Westheimer Institute of Science and Technology in Gainesville, US.

 

‘The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,’ he commented. ‘It’s lucky that we ended up here, nevertheless – as certainly Earth has been the better of the two planets for sustaining life. If our hypothetical Martian ancestors had remained on Mars, there may not have been a story to tell.’
