Stuff leftover after the sun forms usually turns into a system of planets. Some of these planets have solid surfaces, perhaps liquid seas and a gaseous atmosphere; a rich environment for atoms and molecules to come together in complex chemical reactions. Carbon atoms in particular, link together to form complex organic molecules and amino acids. Chemical catalysts speed reactions along. The products of one chemical reaction become the raw material for new reactions. At some level of complexity a catalyst became an enzyme, an amino acid chain became a protein, a loop of chemical reactions became a metabolism, and chemistry became ... biology. BIOLOGY On our own planet, and perhaps countless others - life arose. The DNA molecule, which is the basis of all organic life on Earth, is more intricate by far than any spiral galaxy - because the structure of DNA contains something new - something that was missing from inanimate matter before the origin of life - it contains information. The DNA molecule encodes not only the information necessary to make copies of itself, but the information necessary to ...
