I’m a fan of panspermia<\/em>, particularly the idea the mushroom spores traveled to Earth and gave humans a little extra something. The concept was given a real boost this week with news that components of DNA, nucleobases<\/a>, have been found in meteorites:<\/p>\n

In laboratory experiments, Callahan and colleagues showed how the nucleobases could have formed inside meteorites. Simple chemical reactions involving ammonia, water and hydrogen cyanide \u2014 all ingredients found in meteorites \u2014 produced the wide range of nucleobases the scientists found in the space rocks.<\/p>\n
…Scientists have also found other building blocks of life \u2014 most notably amino acids, the links that form proteins \u2014 inside meteorites.<\/p>\n
While Bernstein said that it\u2019s impossible to discern whether the first life on Earth was built on chemicals that fell from the sky, that possibility is now stronger. \u201cThese molecules are at the core of [life\u2019s] blueprints,\u201d Bernstein said of the nucleobases. \u201cIt\u2019s possible that the presence of these molecules in meteorites made us what we are today.\u201d [Source: Washington Post<\/a>]<\/p><\/blockquote>\n
The other possibility is that those ingredients helped life form elsewhere in the universe, and that life itself arrived on Earth, rather than forming in the primordial soup<\/a><\/em>. As time goes on,\u00a0 evidence (and theories from the likes of Mike Baillee)\u00a0 is growing, and it seems certain that past humans have been affected by bombardments from space. Which means comets, meteorites, dust, red rain, or even mushrooms from space will return one day…<\/p>\n","protected":false},"excerpt":{"rendered":"
