“ ”Primitive “bondmaker” molecules, early precursors of the RNA system, which bind nucleotides together, came into existence way before the first cells. So, too, did bondmaker molecules that developed the ability to join nucleotides together following a template — “copymakers.” These bondmakers and copymakers came into existence through random molecular re-sorting. It was the existence of copymaker molecules that set the process of evolution into motion. Natural selection chiseled living things into existence, but the requisite molecules for evolution — the bondmakers and copymakers — existed before life itself.

Additional quotes by Michael S. Gazzaniga
Spontaneous smiles are different. They utilize a totally different neurologic hardware that is diffuse and arises mostly out of the subcortex and something called the extra-pyramidal system.
This great zone of cerebral activity is where plans are made to speak, write, throw a baseball, or pick up a dish from the table.
The psychology professor Richard Aslin once commented to me that he felt the idea of “consciousness” was a proxy for a whole host of variables correlated with our mental lives. We use “consciousness” as shorthand to easily describe the functions of a multitude of inborn, instinctual mechanisms such as language, perception, and emotion. It becomes evident that consciousness is best understood as a complex instinct as well. All of us come with a bucketful of instincts. Our incessant thought pattern jumps around. We have feelings about one idea, then its opposite, then our family, then an itch, then a favorite tune, then the upcoming meeting, then the grocery list, then the irritating colleague, then the Red Sox, then … It goes on and on until we learn, almost against our natural being, to have a linear thought.
