Canadian Meteorite Has All the Building Blocks for Life

MeteorInteresting article from Tim Barribeau on io9.com:

The argument that life on Earth may have been seeded from the stars just received a major boost, as scientists have found the building blocks of life inside a meteorite that landed in British Columbia in 2000.

The Tagish Lake meteorite landed in January of that year, a streaking fireball that burst into more than 500 fragments which rained down on the lake. In its trip from the outer reaches of the asteroid belt it burned down from 56 tonnes to 1.3, and deep inside the fragments there are the basic building blocks of life, including the amino acids, sugars and hydrocarbons that could have jump started life on our planet.

This meteorite is the only uncontaminated example we’ve ever found, thanks to the quick actions of the people who spotted it. What the researchers have found is that the organic compounds in the rock date back to the early days of the solar system, or possible predate it. A large parent body was formed in orbit around the star with chunks of ice trapped within. Over the billions of years that followed, the ice warmed, and the hydrothermal change altered the organic compounds. The large body has since broken up, and constitutes the carbonaceous chondrites meteorites that make their way to Earth. Within the samples discovered was organic matter that had properties that spanned properties found in other similar meteorites around the world — showing that the differing organic compound makeup of these rocks can come from a common precursor.

    I don’t much care for the seed theory because it dodges the question of how life started.  When I ask how life started, I wasn’t asking for theories on how it arrived here because you don’t understand how it developed here. It had to stat somewhere where it was here or elsewhere. It’s especially useless because a lot of their problems are that there wasn’t enough time for life to develop on earth according to some calculations, but the seeding claim still doesn’t help. It just makes it worse by requiring an even bigger time frame for it to start somewhere else, then magically get all the way to Earth.

    This article shows that life is started from non-living chemical reactions. What more do you want?

    Of course Earth was seeded from the “stars”. The earth is part of the universe isn’t it? It’s been flying through space virtually forever, picking up all sort of cosmic material and leaving some in its wake too. The question is so stupid I can’t believe it. No, the earth is not that special. No, the earth is not the center of life in the universe. 
    The sheer vastness of the universe makes such an assertion ludicrous. We don’t even know if life exists on other planets in our solar system -let alone the entire universe. Hell, we don’t even know what life is. We are a mystery to ourselves.

    It seems that Galileo was never really taken seriously. We still have the retarded perception that we are the center of the universe and “God” just put all those distant stars and phenomenon out there so we could look at the pretty lights in the sky. Ridiculous…

    An alternative to the “it came from the skies” theory (or, depending on which “it came…” theory one is talking about, it may be compatible with what I am about to describe) that seems even more promising to me is this one:

    Basically, all you need is formamide, water, UV light and you can build ALL the main base-pairs of RNA.  Furthermore, through a sequence of dryings and wettings you can build up part of an RNA skeleton.

      Where did formamide, water, and UV light come from and why can it build all the main base-pairs of RNA ????

    A lot of you are just cocky people who like to argue and type too much to fuel your grandiosity.

    This was an interesting read.

      Yes it was an interesting read, unlike your comment.
