GHB: From past to present: evolution and epigenetics.
David Marsh: McCarrison Society, scientific writer – explained, for the less scientific conferees, the meaning of epigenesis: the ability of environmental influences to act upon a genetic mechanism and thus change its expression. Although, in the 19th century and before, environmental influences were believed to be important in directing evolutionary development, for the last 100 years (post Professor A. Weismann) it was thought that proteins from the nucleus built cells regardless of environmental influences. It is now coming to be accepted again that environmental pressures (nutritional, chemical etc) are able to ‘throw genetic switches’. For relevant research check www.brucelipton.com/references.php
