“our genome is less like a static blueprint and more like a piano. The piano keys represent the genome. We each get different keys, and the keys don’t change throughout our life: we die with the same piano keys, or genome, we’re born with. What changes is the sheet music: the epigenetics. That sheet of music determines what tune is played—what genes are expressed—and those genes determine our traits—everything from IQ to hair color.”
