<human>:  Summarize the current research on the role of epigenetics in development and disease.
<bot>: Epigenetics is the study of how environmental factors can influence gene expression and affect development and disease. Recent research has provided evidence that epigenetic mechanisms are highly involved in development, with environmental exposures such as diet, stress, and toxins potentially altering gene expression and contributing to a variety of health and developmental outcomes. Additionally, epigenetic factors have been linked to numerous diseases, including cancer, obesity, and autoimmune conditions. These findings suggest that epigenetics may be an important contributor to both development and disease, and further research is needed to understand the full extent of its impact.
