Evolutionary constraints or opportunities?

Bio Systems - 1 Sept 2014

Sharov Alexei A

Abstract excerpt

Natural selection is traditionally viewed as a leading factor of evolution, whereas variation is assumed to be random and non-directional. Any order in variation is attributed to epigenetic or developmental constraints that can hinder the action of natural selection. In contrast I consider the positive role of epigenetic mechanisms in evolution because they provide organisms with opportunities for rapid adaptive...
