Epigenetics and its importance to adaptation in a changing climate

"The current pace of climate change exceeds historical events by 1-2 orders of magnitude, which will make it hard for organisms and ecosystems to adapt. For a long time, it has been assumed that adaptation was only possible by changes in the genetic makeup - the DNA base sequence. Recently, another information level of the DNA, namely epigenetics, has come into focus. Using a fish species from the Baltic Sea, the three-spined stickleback, an international team investigated whether and how epigenetics contributes to adaptation." - Excerpt from Helmholtz Centre for Ocean Research Kiel
