Genome Plus Three

Your genome, 46 chromosomes and the 25,000-30,000 genes on them, was once thought primarily to be in charge of determining your development, including your height, skin hue, eye color, and on and on. In their book Evolving Ourselves, authors Juan Enriques and steve Gullans, PhD, describe three additional layers that have a profound impact on how your genes express themselves and how your brain and body develop and function. These layers are:

·         Epigenome: the complex array of matter surrounding your genes

·         Microbiome: the trillions of bacteria in your body

·         Virome: trillions of viruses that far outnumber both your body’s cells and microbes
