But it seems to me that another omission makes itself felt even more visibly (to a wider readership, that is): Jean Piagel's epigenetic theory
of human development.
Further, in speaking with researchers in the field and reviewing the scientific literature, it is evident that the medical and scientific community generally believes that epigenetic theory
is valid and that research in this area will likely shed much light on disease causation.
According to epigenetic theory
, changes in the genome can happen at any time through the impact of environmental factors on the expression of genes over time.
Epigenetics brings a new perspective on the old problem and new analytical tools that will help to test the epigenetic theory

of cancer that locates control of single cell growth in higher (tissue and organ) levels of biological organization.
Revisions of this theory began with the Herder reviews of 1785 and continued through the late encounter with Johann Blumenbach's epigenetic theory
