Stephen Jay Gould (jan 1, 1941 – jan 1, 2002)

Description:

Stephen Jay Gould(1941-2002): His most significant contribution to evolutionary biology was his theory of punctuated equilibrium, which is the idea that evolutionary development is marked by isolated episodes of rapid speciation between long periods of little or no change. Gould also developed the concept of "deep time," the vastness of earth’s history, a history so ancient that we can comprehend it only as metaphor, which involved deliberately rejecting the biblical description of earth's past for nearly incomprehensible eons.
