Comets could have seeded life on Earth

A new experiment simulating conditions in deep space reveals that the complex building blocks of life could have been created on icy interplanetary dust and then carried to Earth, jump-starting life.

Chemists from the University of California, Berkeley, and the University of Hawaii, Manoa, showed that conditions in space are capable of creating complex dipeptides – linked pairs of amino acids – that are essential building blocks shared by all living things. The discovery opens the door to the possibility that these molecules were brought to Earth aboard a comet or possibly meteorites, catalyzing the formation of proteins (polypeptides), enzymes and even more complex molecules, such as sugars, that are necessary for life.

A note to fundies and muslims... if you consider this an insult to your religion, GOOD. Grow the fuck up and get over yourselves.

Proof?

Interesting read, but I couldn't provide a very good commentary on it. I've always had trouble understanding astronomy. Which is a disadvantage, because it doesn't allow me to interpet the news about those kind of things, and I just take their word for it.

I suspect it is a bit more complicated than your fairy tales.

There is nothing fundamentally new here. The basic concept is chemistry for formation amino acids exists either in environment we can directly observe to exist, or can easily and convincingly deduce deduce to exist, which then can be connected to locations on earth where conditions can reasonably be deduced to have been stastitiscally favorable to assembly of such amino acids first into a self replicating formation, then into a package which can mor efficiently assemble the material and energy needed to further this replication.

The only major effect is to point out a part of abiogenesis process which is still not only still in operation and subject to direct observation, but also indisputably had always been in operation continously throughout earth's history.

Other parts of abiogenesis runs into the statistically issue of why is there no evidence of life arriving independently multiple times on earth, resulting in totally incompatible biochemistry and evolutionarily totally separate lineages of life. To this we have only a partial answer.

If they say actual living cells came here on comet dust, that would be different.

Much as that theory about crystals is rubbish compare to science, it still claims the insurmountable advantage over creationism - Crystals exists. You, on the other hand, are sucking enthusiastic a nonexistent cock.

lol! Like the existence of crystals proves anything...

Queer-boy? Can you explain that bizarre remark? What fantasy???

In fact, what the HOLY FUCK are you even talking about?!?!

Nothing as it may prove, it stills proves more than your bible ever could.

As to queer, it is not me who dreams of being one with a hairy illiterate dead failed carpenter who are claimed to have no interest in natural attachment to women.
