Did you know that normal DNA is only 10% of our genome? What do the other 90% do? Half of them are "evolutionary genetic residues" of microorganisms, worms, fish and thousands of DNA sequences belonging to numerous viruses. The second half of our genetic material produces "strange" molecules that regulate how cells work. These sections of our DNA are called the "dark" genome. Twelve real-life stories told in surprisingly lively language will lift the veil of secrecy for you, shatter the myth that the environment and lifestyle do not affect transmitted hereditary traits, and answer questions about how heredity and health are linked. You will find out whether a person can inherit their parents' diseases, what is the connection between oncology and epigenetics, whether leadership qualities are inherited, and much more.
