Speciation does not necessarily promote evolutionary change; rather, speciation 'gathers in' and guards evolutionary change by locking and stabilization for sufficient geological time within a Darwinian individual of the appropriate scale. If a change in a local population does not gain such protection, it becomes-to borrow Dawkins's metaphor at a macroevolutionary scale-a transient duststorm in the desert of time, a passing cloud without borders, integrity, or even the capacity to act as a unit of selection, in the panorama of life's phylogeny.
Stephen Jay GouldWe are storytelling animals, and cannot bear to acknowledge the ordinariness of our daily lives.
Stephen Jay GouldWe who revel in nature's diversity and feel instructed by every animal tend to brand Homo sapiens as the greatest catastrophe since the Cretaceous extinction.
Stephen Jay GouldPaleontologists [fossil experts] have paid an exorbitant price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we almost never see the very process we profess to study.
Stephen Jay GouldLife shows no trend to complexity in the usual sense-only an asymmetrical expansion of diversity around a starting point constrained to be simple.
