quantum evolution

Show Summary Details

Quick Reference

The sudden spurt of diversification in an evolutionary lineage. Typically it results when a population shifts into another adaptive zone. Initially the number of individuals will be small, and rapid genetic and phenotypic change is feasible in such circumstances, particularly if the new niche is unoccupied. The concept of quantum evolution has been given special significance in the theory of punctuated equilibrium.
