punctuated equilibrium theory

基本解释

Mr Gould's opponents referred to punctuated-equilibrium theory as evolution by jerks.
ECONOMIST: Stephen Jay Gould
Though punctuated-equilibrium theory as originally conceived has made few converts, the role of accidents in evolution is more widely appreciated, as asteroid collisions and nearby supernovae are recognised as hazards that can wipe out whole groups of organisms arbitrarily.
ECONOMIST: Stephen Jay Gould
Those who worked with what was alive in an infinity of yesterdays complained that even though they had no good explanation of why punctuated-equilibrium theory worked, you couldn't argue with the evidence in the rocks, maths or no maths.
