Humans have displayed evidence of epigenetic changes such as DNA methylation, differentiation in expression, and histone modification due to environmental exposures. Carcinogen development in humans has been studied in correlation to environmental inducements such as chemical and physical exposures and their transformative abilities on epigenetics.
Behavioral epigenetics is the field of study examining the role of epigenetics in shaping animal and human behavior. [1] It seeks to explain how nurture shapes nature, [2] where nature refers to biological heredity [3] and nurture refers to virtually everything that occurs during the life-span (e.g., social-experience, diet and nutrition, and exposure to toxins).

Epigenetics of anxiety and stress–related disorders is the field studying the relationship between epigenetic modifications of genes and anxiety and stress-related disorders, including mental health disorders such as generalized anxiety disorder (GAD), post-traumatic stress disorder, obsessive-compulsive disorder (OCD), and more.
While the psychological impact of climate change is largely negative, related social engagement can have positive effects on mental wellbeing. The psychological impacts of climate change concerns effects that climate change can have on individuals' mental and emotional well-being. People experience a wide range of emotions as they grapple with ...
Multiple epigenetic factors can influence the state of genes and alter the epigenetic state. Due to the multivariate nature of environmental factors, it is difficult for researchers to pinpoint the exact cause of epigenetic changes outside of a laboratory setting. [38]
It is not the protein sequences that account for the differences in physical characteristics between humans and apes; rather, it is the epigenetic changes to the genes. Since humans and the great apes share 99% of their DNA, it is thought that the differences in methylation patterns account for their distinction.
These behavior changes include: engaging with the public about climate change, contributing at a personal, communal, cultural and political level by supporting effective change through activists, scientists, and policy makers, and finally nurturing psychological resilience to the destructive impacts climate change creates now and in the future.
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.
