by Shea Robison (@EpigeneticsGuy) Pesticide Methoxychlor Promotes the Epigenetic Transgenerational Inheritance of Adult-Onset Disease through the Female Germline Policy implications: As this research involves the epigenetic effects of exposure to a very common pesticide and insecticide, there are all sorts of implications for agricultural policies and FDA food safety regulations. These results also address the transgenerational … Continue reading Research Paper of the Week: Pesticide Methoxychlor Promotes the Epigenetic Transgenerational Inheritance of Adult-Onset Disease through the Female Germline
by Shea Robison Instead of the evolution of modern genetics and the Modern Synthesis as a progressive process of gradually narrowing in on the one true path of scientific knowledge, the history of genetics suggests that genetics could have developed along any number of alternate pathways, including paths in which epigenetics was accepted in one form … Continue reading The Epigenetic Evolution of Genetics (and Epigenetics)
by Shea Robison Epigenetics is an emerging field of research related to, but in many ways distinct from, genetics. While the basic premises of genetics are widely known and accepted, what is much less well-known is that there are biological processes ‘above’ the genome called collectively the epigenome (from the Greek root epi-, meaning ‘above’ … Continue reading How is Epigenetics Different from Genetics?
by Shea Robison The highly political and ideological history of epigenetics discussed here and here and here helps to explain why epigenetics has only just now emerged as a signficant field of scientific research, as well as why epigenetics has such a mixed reception even today. Below are two examples of the chilling influence of world politics … Continue reading Epigenetics and Two of its Cold War Casualties
by Shea Robison In addition to the reasons discussed here and here, another cause for the split between genetics and epigenetics, and the different trajectories of each, has to do with geography and world events. As mentioned before, the fields of genetics and embryology – which was where most of the work on epigenetics was being … Continue reading History, Part III: Epigenetics and the Dustbin of History
by Shea Robison (@EpigeneticsGuy) As discussed in the previous post in this series, if epigenetics had been accepted into the mainstream of genetics at this early stage of its development, epigenetics likely would have been incorporated into the overall theoretical structure of genetics without too much disruption. Instead, for many years the field of modern genetics disqualified epigenetics … Continue reading History, Part II: Epigenetics and the Politics of Science
by Shea Robison (@EpigeneticsGuy) In the history of modern Western evolutionary theory, the first use of the term epigenetics is generally attributed to Conrad Waddington in an article published in 1942. In this article Waddington used epigenetics as the name for the study of the causal mechanisms through which genes bring about their phenotypic effects and … Continue reading History, Part I: A Brief History of Epigenetics
