Econintersect: Researchers at California Institute of Technology, Pasadena [Caltech] might have harnessed DNA in a artificial primordial soup that exhibits "intelligence". According to the Primordial Soup Theory life began on earth approximately 3.5 billions years ago. The primordial soup then was an ocean of chemical molecules which combined under the action external energy (solar, thermal) to form larger molecules and make amino acids, the building blocks of protein. Some of these molecules could replicate themselves and thus began a complex sequence of evolutionary drama which resulted in life. All life forms we know today are based on two classes of complex amino acids, Ribonucleic acid or RNA's, and Deoxyribonucleic acid or DNA's.
Follow up:Artificial Neural Nets modeled after interconnections in our brain have been routinely simulated on computers. An artificial neural network (ANN), usually called neural network (NN), is a mathematical model or computational model that is inspired by the structure and/or functional aspects of biological neural networks. A neural network consists of an interconnected group of artificial neurons which processes information using a "connectionist" approach to computation. Such Neural Nets have demonstrated learning capability and have been successfully used in narrow domains and tasks.
