Challenging the Modern Synthesis

The formation of new species was thought to result from a slow process of Darwinian evolution, but evidence indicates it can occur suddenly. The organism was thought to be passive, playing no role in evolution, but it can affect the evolution of its descendants because of its mobility, choices, control of the environment, and adaptability. Developmental processes were thought to be irrelevant to an understanding of evolution, but the enormous growth of epigenetics suggests that these processes can play an important role in evolutionary change. Acquired information can be passed to progeny without changing DNA sequences, and information can be inherited for a period in the absence of the initial environmental trigger. All this evidence suggests that evolutionary theory is evolving.
