Summary:

Ever since the pioneering work of Darwin and Wallace, evolutionary biologists have attempted to understand the evolutionary dynamics of genetic systems. A range of theories on evolutionary ratesfrom static to gradual to punctuated to quantumhave been developed, primarily by comparing morphological changes over geological timescales as described in the fossil record. Recent studies, however, are beginning to change the way that we view evolutionary patterns and processes. Newpaleontological, experimental, molecular, and genomic investigations are providing a tremendous amount of novel data and
