Thirty-thousand-year-old late Pleistocene bison bones discovered in permafrost at a Canadian goldmine have provided scientists the opportunity to establish means for determining how animals adapt to rapid environment change. A study by the University of Adelaide's Australian Centre for Ancient DNA (ACAD), in collaboration with Sydney's Victor Chang Cardiac Research Institute, published by the online journal PLoS One, carried out an analysis of special genetic states associated with turning genes on and off without changing DNA sequence. These type of changes that scientists term "epigenetic" changes may occur rapidly between generations, faster than the "standard evolutionary processes" change.
