The finding
What the evidence shows
Eldredge and Gould introduced punctuated equilibria in 1972, before the 1980 Alvarez impact hypothesis. It describes long evolutionary stasis punctuated by geologically rapid speciation, not a merger of geological gradualism and catastrophism created by the KT impact discovery. Dan conflates distinct theories and timelines.
