Just in at PhysOrg.com. Non-dividing brain cells quickly undergo epigenetic changes.
“It was mind-boggling to see that so many methylation sites — thousands of sites — had changed in status as a result of brain activity,” Song says. “We used to think that the brain’s epigenetic DNA methylation landscape was as stable as mountains and more recently realized that maybe it was a bit more subject to change, perhaps like trees occasionally bent in a storm. But now we show it is most of all like a river that reacts to storms of activity by moving and changing fast.”
So much for the view that the genome is rather static, and that the major dynamical changes to it involve random mutations. Instead, we have a view of a dynamical DNA that is entirely capable of change via interactions with its environment. Only integrated systems can function dynamically like this. And Darwinism trying to explain the rise of this level of dynamism is like trying to put a square peg into a round hole.
