For next week's lab meeting I would like to discuss the importance of transgenerational epigenetic inheritance in evolution. I selected a paper which gives a nice overview of potential mechanisms and some examples of transgenerational epigenetic inheritance. The paper is already a bit "old" (1.5 year already) and the discussion is focussing on human health, but it gives a nice overview.
Transgenerational Epigenetic Inheritance: Myths and Mechanisms
Cell: Volume 157, Issue 1, p95–109, 27 March 2014
Summary: Since the human genome was sequenced, the term “epigenetics” is increasingly being associated with the hope that we are more than just the sum of our genes. Might what we eat, the air we breathe, or even the emotions we feel influence not only our genes but those of descendants? The environment can certainly influence gene expression and can lead to disease, but transgenerational consequences are another matter. Although the inheritance of epigenetic characters can certainly occur—particularly in plants—how much is due to the environment and the extent to which it happens in humans remain unclear.
