They were talking about the punctuated equilibrium theory many years ago. It makes sense. CHANGE drives evolution. When things are relatively stable, there is no biological incentive favoring new forms.

True. To give a few examples, the Carboniferous Period was known as the Age of Amphibians. A warm climate with lush swamps and giant dragonflies. When the Permian Period came, conditions got cold and dry, the swamps vanished, and most amphibians went extinct. Reptiles then took over and ruled the Earth for millions of years. Mammals came along, but they were small, rodent-like scavengers. Only after the great big asteroid came and obliterated dinosaurs did mammal evolution take off.
