Extending Darwinism

January 12, 2009

In the light of epigenetics, old views of macroevolution must change. If wide-ranging epigenetic and genetic changes occur in stressful conditions, they are likely to have many effects on an organism's form and function, its phenotype. This implies that conditions requiring novel adaptations to cope with them are often the very same ones that spur the massive epigenetic and genetic alterations conducive to rapid evolutionary change. A firm linkage between the production of new variation and its subsequent selection, something forbidden within [Modern Evolutionary Synthesis], grows ever clearer.
