Although each organism has a unique genome, a single sequence of genes, each individual has many epigenomes. An epigenome consists of chemical compounds and proteins that can bind to DNA and regulate gene action, either by activating or deactivating them or producing organ- or tissue-specific proteins. As it is a highly dynamic material, it can provide a large amount of information to shed light on the evolution of the various tissues and organs that make up the body. Now, a team from the Institute of Evolutionary Biology (IBE), a joint center of the Spanish National Research Council (CSIC) and Pompeu Fabra University (Barcelona), has carried out the largest study to date on the regulatory elements in the genome of primates.
