Foraminifera, grow by a process of discrete, stepwise additions of elements to an already existing morphology. While there has been a spectacular progress in defining molecular relationships between different foraminiferal taxa and while our knowledge of morphology of recent and fossil foraminifera is substantial, we still do not know how genetic codes are translated into actual chamber shapes and overall shell patterns. In order to better understand this, it is necessary to construct more realistic models of morphogenetic processes (Tyszka & Topa 2005).
