The gradual model of speciation holds that species originate by slight morphological changes over long time spans. For example, sedimentary rock layers ofen hold veritical sequences of fossilized shelles of foraminiferans. The sequnce reflects graduatal morphological change. (From my Biology 101 book: 'Biology: The Unity and Diversity of Life').
