Evidence Found for Origin of Genes

Evidence Found for Origin of Genes: "Evidence compiled by a team, led by Nobel laureate Walter Gilbert, supports the theory that all genes in all organisms that ever lived on Earth consist of a small number of basic building blocks. These blocks were shuffled and recombined during the past 3-4 billion years to form a dazzling variety of simple and complex proteins that make up life as we know it. The genes carry instructions for making proteins that do everything from allowing bacteria to metabolize methane gas to aiding humans to think."
