Life As We Know It Nearly Created in Lab

[Ichingcarpenter]

Some chemical reactions occurred about 4 billion years ago — perhaps in a primordial tidal soup or maybe with help of volcanoes or possibly at the bottom of the sea or between the mica sheets — to create biology.

Now scientists have created something in the lab that is tantalizingly close to what might have happened. It's not life, they stress, but it certainly gives the science community a whole new data set to chew on.

The researchers, at the Scripps Research Institute, created molecules that self-replicate and even evolve and compete to win or lose. If that sounds exactly like life, read on to learn the controversial and thin distinction.

Know your RNA

To understand the remarkable breakthrough, detailed Jan. 8 in the early online edition of the journal Science, you have to know a little about molecules called RNA and DNA.>>>>snip

Joyce insists he and Lincoln have not created life: "We're knocking on that door," he says, "but of course we haven't achieved that."

Only when a system is developed in the lab that has the capability of evolving novel functions on its own can it be properly called life, Joyce said. In short, the molecules in Joyce's lab can't evolve any totally new tricks, he said.

1. that is very cool....

Wow!
