Vivid imaginations, have/have-not structure, adds to the reason that humans are more susceptible to mental health and addiction than other primates. Peak of risky behaviour (more specifically in males) have a huge public health implication. The environment shapes the epigenome, which regulates the way that genes are expressed in order to influence the phenotype. While we use the image of toxicants to denote an environmental stressor here, environmental stressors can come in the form for nutritional, physical, or psychosocial stressors. Epigenetics refers to the study of chemical modification to dna that are associated with changes in the way genes are expressed or turned on, and are essential for normal development within mammals. In contrast to genetic studies, which emphasize the gene sequence with which one is born.
