Evidence that evolutionary change is not always a smooth process

ONE of the most acrimonious disputes in biology is between those who
believe that evolutionary change is a smooth and gradual process and
those who think it happens suddenly-evolution by creeps versus
evolution by jerks, as some of the protagonists unkindly put it. The
gradualist model tends to be favoured by those who study things that
are still alive, while the punctuated-equilibrium model, as the
sudden-transition way of looking at the world is known in the trade,
finds its support among those who study fossils, and who feel that the
evidence from the rocks favours their view.
