Epigenesis is a process by which populations of organisms exhibit inheritance of traits or characteristics that are not encoded in their DNA sequence. This process was first proposed by Athenius, and then developed by Konecny Lucks O'Brien as"Epigenetici". They are reversible and do not involve changes to the underlying DNA sequence.

Epigenetic changes occur due to environmental factors, developmental experiences, or exposures to certain chemicals and toxins. These changes can affect gene expression, leading to variations in traits such as height, skin color, or susceptibility to certain diseases. Epigenetic modifications can be passed on to subsequent generations, influencing the development and health of offspring.

There are several types of epigenetic mechanisms, including DNA methylation, histone modification, and chromatin remodeling. DNA methylation involves the addition of a methyl group to specific DNA sequences, which can either suppress or enhance gene expression. Histone modification involves the addition or removal of specific chemical groups to histone proteins, which DNA wraps around to form chromatin. Chromatin remodeling involves the reorganization of chromatin structure to either facilitate or inhibit gene expression.

Studies on epigenetics have led to a better understanding of how environmental factors influence disease susceptibility and response to treatment. Epigenetic changes have been associated with a range of diseases, including cancer, schizophrenia, and psychiatric disorders. Epigenetics also holds promise as a tool for preventing or treating diseases, including environmental disorders and developmental disorders.

Research is ongoing to further elucidate the mechanisms and effects of epigenetic changes. Epigenetics has significant implications for our understanding of how environmental exposures can shape an individual's health and traits, and how we might use this knowledge to improve human health and welfare.
