Now this is absolutely facinating.  

Two researchers at the Scripps Institute isolated two unrelated enzmatic RNA molecules that were able to each replicate themselves given a supply of resources - 'food'.

But not only that, each RNA molecule undergoes mutations in the process of replicating.  Mutations that lead to a change in traits over the course of many generations.  But because these generations are at the molecular level, the scientists could make observations in the time span of days.  

The two researchers pitted the molecules against one another and the result was a mimicking of a classic case of Darwinian evolution as each molecule competed for 'food'.

Evolution in a Test Tube - Darwinian Evolution at the Molecular Level


This is yet another example of experimental observation of evolutionary process in action.  Sure, it was artificial, but it shows the process working - just like in nature.  

Seeing that molecules can replicate, mutate, compete, and evolve at the molecular level is also very compelling evidence that abiogenesis can, and did, take place here on earth around 3.6-4.0 billion years ago.

Chalk another one up for Darwin.

You can't begin to imagine my envy.

I'd love to be doing that...

That kind of research, i mean. Not competing for food.

Scientists assert (by Lester):

Ha Ha. (...) I've told you people endlessly about my evidence but you don't want to show me yours - you just assert.

Would we see a mammal by the water's edge "suddenly" start breathing underwater(w/camera effect of course)?
