Life As We Know It Nearly Created in Lab is an interesting article about some scientist that created molecules that self-replicate and even evolve and compete to win or lose. This only proves is that life can be designed.
The big mystery of life is how it began. It's pretty evident that life has evolved from the simple to the complex through natural selection, but how did it start?
If life occurs randomly then complex life is likely to be extremely rare. I'd like to think that early life was designed with the ability to evolve as a built in mechanism to increase its chances for survival.
