MOESM1 of In silico evo-devo: reconstructing stages in the evolution of animal segmentation

Additional file 1: Figure S1. Cell-cell signalling allows for robust development in the absence of posterior morphogen (but not always) (transient signal, CCS). A) This individual evolved to be very robust. It usually makes eight segments and only in rare cases seven good segments and one short segment. B) This individual did not evolve to become very robust despite the presence of cell–cell signalling genes. Nevertheless, it is usually able to make many more segments than the individuals evolved without cell–cell signalling. The histograms represent the variation in phenotypic outcome when an individual{\rsquo}s development is repeated 50 times. In the histograms, the dark bars represent the good segments and the lighter bars the too short segments. See “Methods” for further explanation
